So I got this motorcycle at a auction. It did not start because the battery is dead. I took it to this dealership to have it looked over and they said they could not get it started. The cables to the throttle we're not even hooked up. So $160 later I take it back to the auction place which is mind you at least 3 hours from me and they bring out a jumper and start it right up. Explain that one

I bought my first BMW through Jeff Koenig, very knowledgeable sales person . helpful and was able to help me with all my questions. Bmw is lucky to have him. I’m sure I’ll be giving return business in the future.

Jeff was beyond helpful and even came in on Monday when they are closed to help me close the deal on my 2023 BMW S1000rr. He had answer for every question i asked and was prompt with the replies. He even mentioned they get a 10% discount on akrapovic accessories which i ended up using to buy a new slip on for my bike! Definitely recommend!!! Ask for Jeff!!!

I can't express my feelings enough, if I could I would give 10 stars. Great experience and great atmosphere. Every time I go there I spend hours in the dealership and I learn ton of new things and meet great people.I ended up buying my first motorcycle form here, and I am glad i did. I was fortunate to meet with Jeff, he made my buying experience fun, flawless and easy. He got me a great deal and massive discount on my gears. On top of that, BMW has a program that pays for your MSF course and big check towards your gears. Best experience ever.

From sales (Jeff) to service (Mike and Tim) these guys are the best. They also host the best bike event of the year. I highly recommend this dealership if you're looking for new or used BMW bikes or services.Also I cannot wait for 2024 when they move to their new bespoke facility located off 275 and 7 mile.

Thank you for the brandnew R18 100 year anniversary edition!You guys are amazing. Once I walked in, it took less than an hour to get all the paperwork done. I was offered a test drive as well, while HD won't let you drive. Also, I gave my 2017 HD 883 as a trade in and they offered me double what the HD dealer offered me. Also i got 3000$ cash credit and first 4 payments free!! I highly recommend them!

Never had a bad experience here. This group manages themselves on their own very well. Never had to wait an extended amount of time for service, & always taken care of promptly.

Had a fuel pump recall done. Super nice service writer. They squeezed me in and got me out in the same day. Tech took really good care of my bike. Went above and beyond and did a few little things for no extra charge.

Wonderful experience buying from Raina over the phone. Easy, quick transaction and got me hooked up with a shipping company she knew and trusted. Bike arrived safely and she got me all of the paperwork before it even got here. Thanks again y'all.

This "is" absolutely the best place to purchase a motorcycle, if your thinking of buying a bike these guys will. I mean will, take care of you no if ands or butts period. No one else compares.

Mark Stewart

I had an excellent experience while buying a S1000RR. Raina answered all of my questions. Very smooth, easy process. They delivered it exactly at the time I requested. Then after I had put 600 miles on it, they picked it up for it's first service. Then dropped it off at the same time again. I have had several questions about parts and service. Raina is fast to reply to emails. The owner is a good guy too. He also owns Ducati Detroit. I wish they sold Aprilias!

If you’re in the market for a BMW Motorcycle ONLY go to these guys. 1. Purchased, now 3 motorcycles and these guys have ABOVE & BEYOND better service and experience all around. 2. I’m in the car sales business and I was extremely impressed by the experience. That should say enough. From sales, to parts and techs, these are your people. Jeff K, I can’t thank you enough for everything. Excited for my new 2022 S1000rr :) - Josh

I stopped by to check out R 1250 GS's for my first adventure bike down the road. Jeff was very friendly and incredibly informative. I'll certainly be in again when it's time to buy.

Dan G

20:36 06 Oct 22

Great BMW dealer! I came from out-of-state to pick up a bike and was treated wonderfully by all the staff. I had a bunch of questions for the service department and they were very helpful. Gave me all the service records, made suggestions for products and got me ready for a long cross country ride home. No one was too busy to help me - rare these days. I will be sporting my new BMW Motorcycles of SE Michigan t-shirt all over So Cal. My only complaint is this dealership is too far away for my next oil change! Highly recommend these guys for your next purchase/service!

Brian Vosko

09:51 05 Oct 22

Hands down, the BEST MOTORCYCLE DEALERSHIP I have ever been in contact with!After deciding to trade my Aprilia Tuono Factory for a BMW S1000R, Raina and Charlie did everything they could to help me with the deal. Every discount, promotion and a very respectable trade offer was provided without tension or haggling.As someone new to BMW motorcycles, I had a million questions and the parts and service department, led by Mike - were friendly, courteous and very professional.As for the bike itself, flawless and beautiful! With 1,200 miles and a trackday at Grattan last weekend, I have nothing but love for her.If your in the market, do yourself a favor and reach out to BMW of Southeast Michigan - SIMPLY THE BEST!

Much like its sister store, Ducati Detroit, you can expect warm, friendly, knowledgeable staff and customer service for any of your Motorrad needs. People here are excited about the sport and want you to get excited, too. As always, there’s no pressure other than to come and sit on bikes, talk bikes, dish on upgrades, and learn. I’ve bought and sold about 8 bikes between BMW Motorcycles SE MI and Ducati Detroit and I’ve only had good experiences from top to bottom. If you’re a newer rider or a woman who’s had poor service or support at other shops, come here! The used inventory is also fantastic- and Raina and Jeff will stay in touch with you if what you’re looking for isn’t available. Bonus: you can take just about any bike you’re interested in for a test ride. Not many dealers will do that, but as long as your endorsement is good, you can actually try before you buy. Parts, service, and support is par excellence- Mike in parts is a guru and can help you kit your bike out exactly as you’d like it. I can’t say enough good things. Thanks for all the fantastic service, Charlie and Co!

Dealing with parts today (Joseph) was what you get from a people that care. I’m from Canada and on my 6th day of a 2 week trip around Colorado and Utah my K1200S broke on the road (a plastic gas connector with the fuel pump) middle of nowhere, and this guys found the part and placed on FedEx express delivery so I will receiving it tomorrow. They even connected me with their service department to ensure I have all I need to fix it and continue my trip.Top notch customer service, and thank you guys

Traded in my 2010 Bmw s1000rr and got the 2022 s1krr. The sales manager Raina and a sales associate Jeff were great. They were super helpful with the process and answered any questions I had.Joe in parts and service is also awesome always is helpful and got my bike done faster then scheduled !

Cybbi Barton

18:46 03 Aug 22

I don’t know who oversees payroll, but I hope they give Joe a raise. Joe helped me out with what I needed, questions I had, and even took time to walk me around the inventory to inspire my next purchase. I loved being in the store and will absolutely come back to buy my next bike…all thanks to Joe.

02:14 09 Jun 22

(1 year update) One of the best -perhaps only- sales experiences that I've had. The sales people are extremely knowledgable and non-pushy. I purchased my fully loaded 2021 F900XR here about a year ago. I have nothing but great things to say about them, the service technicians are masters of their craft. And, not to mention, the bikes are superb.

Great place. Very helpful and informed sales staff. No hard sell. Ended up buying a bike. Can’t recommend the place enough.

David McGuire

I enjoy giving positive reviews, and gave a very positive one for this dealership after purchasing a new BMW R NineT from them a few years ago. I'm looking to purchase another, so I naturally returned to the dealership that had treated me well before. I was disappointed to discover that they now add a $541 Dealer service charge above and beyond what they charged before. Seems they have a new owner who quietly pads the bill. The sales staff remains courteous and helpful, but the bottom line no longer is competitive with their competition. I highly recommend shopping elsewhere for your next BMW motorcycle.

Adam Youngblood

14:33 11 Apr 22

Talk about a great motorcycle sales experience. No pressure, great advice and a friendly environment. I mainly worked with Jeff throughout the purchase process of my R1250GS and it was a breeze, but even when I called and Jeff wasn't in or busy, the other staff went above and beyond to help me with my matter. Thank you BMWMSEM!

ENGELS MERCHAN

15:57 21 Mar 22

To all the staff of BMW Michigan I am Engels Merchan with great enthusiasm I applied on Wednesday, March 2, 2022 for the purchase of a 2022 BMW GS 1250 Adventure 40 edition, that same day the financing was approved and the papers were sent to me by email to sign them and return them by mail, so on Thursday, March 3, I sent them complying with all the requirements, such as the insurance policy, on Friday, March 4, Miss Raina informed me that she had received everything well and that in two weeks maximum The motorcycle arrived at my house. Today is March 21 and my motorcycle still hasn't arrived, I work in a car dealer in Memphis TN, I'm a broker and a car salesman, we have sold cars even in the state of New York and we always meet the delivery times that are not more than three days. This non-compliance disappoints me a little about the brand, I hope that the bike does not disappoint me and that the moment I drive it I forget everything, it's a bad time.

16:38 22 Feb 22

No pressure sales and a good atmosphere. Respectful and engaging. Prices are "what you see is what you get" with no hidden fees.Honestly the best dealership experience I've ever had. You can shake hands with the salesmen there and not pull your hand back with slime on it. Ask for Jeff.

D Massey

17:46 09 Feb 22

Been doing business with them for almost 20yrs - truly an outstanding enterprise , and more than simply a business. Professional, friendly, efficient, and customer service oriented. As good as the bikes are I’ve been riding BMW’s as long as I have in large part due to how good this dealership is and the way they treat customers. From inventory to parts to service they are “best of the best”

I just purchased my second BMW from this dealership today. I bought a new R18 Classic. I bought my very first motorcycle in Tennessee in the 70s and have since had a couple dozen bikes form many dealerships from many states. As a result I have had many different experiences working with dealerships on new bike purchases. Today’s purchasing experience was by far the best. To say they exceeded my expectations would be an understatement. I was pleasantly surprised at the attention and ease of this purchase. Charles and the entire staff were attentive, friendly, knowledgeable and professional. They definitely went above and beyond. I currently have 6 motorcycles and am always looking for the next one. I say all that to say this, if you are considering a new or used motorcycle please give these guys an opportunity to help you. You will not be disappointed. They have earned a customer for life. Great riding to all and thanks to a terrific dealership.

BMW Motorcycles of Southeast Michigan is a top notch dealership.The sales staff is excellent and knowledgeable about the motorcycles.The service department has very knowledgeable and dedicated mechanics.

A comfortable, capable, and knowledgeable sales staff will provide you with all the information you would need in deciding your motorcycle purchase. Not to mention you have a great opportunity to test ride a motorcycle on some of the most beautiful and fun roads of SE Michigan.I really felt that the sales staff could not have been more professional and understanding of my specific situation and needs. They want to help you make the right decision for your riding style, financial situation, and experience. They will help you understand the bike that best suits you. All the while, there is no pressure or arrogance to move you past your own finances and wants. You never need a motorcycle, but if you want a motorcycle, definitely consider the engineering and performance behind each BMW. Very impressive. I would strongly recommend BMW Motorcycles of Southeast Michigan.

18:19 05 Oct 21

Great buying experience. Jeff is no pressure and very knowledgeable about the R18B I purchased and other motorcycles I was interested in. Reyna helped me with technical knowledge of riding gear too.They gave me a fair deal on my GS that I traded in and overall been a very comfortable dealership to hang out at.I’m writing this about two weekends after my purchase and already did the first service and that experience with Michael and Corey was efficient and painless.Met the new owner Charles a few days ago too and want to compliment him on such a good team he has in place. I would highly recommend this dealer to anyone for new or used motorcycles - top notch place.

Purchased a 2020 F850GSA from BMWMCSEM in Dec. 2020. Great service. Good price. Dealing with Jeff in sales has been a pleasure every time. Service has always been prompt and enabled me to wait on site for everything except more significant work (like tires that needed to come in the next day).The dealership is under different ownership now. Fall maintenance will be my next planned opportunity to see how it is under them.

Thanks to the sales advisor Jeff Koenig from BMW Southeast Michigan and his team, I am here giving FIVE STARS.I had a 2021 GS850 Adv (an amazing motorcycle) and by a personal reason, I decided to buy the 2021 GS1250 Adv.During a two months process (from the time that I took the motorcycle back to BMW Southeast Michigan until get the new GS1250), Jeff helped me with a incredible patience and professionalism, listening and amazing customer care.I had exactly what I expected from BMW without any exemptions from the quality of their products to the excellence on the attendance and quick response to their customers.Thank you Jeff Koenig, BMW Southeast Michigan and BMW Corporation.

Ryan Webster

14:04 01 Jun 21

Had a great buying experience at Southeast Michigan BMW. Jeff Koenig was a great salesman. Knows his product well and answered any and all questions I threw at him. I even requested that he assist me with the strapping of the bike to my trailer, to which he showed me the proper way to do it. Great experience and would buy from them again.

Visited the dealership back in October to look at their stock and was thoroughly impressed with the dealership as a whole. Jeff took the time to answer all of my questions even though I told him I was just looking. Went back in this past Saturday with my wife to check out several bikes and once again Jeff greeted us and helped answer all our questions. Ended up putting a deposit down on a unit. Can't wait to get the deal finalized!

Just went to look at some adventure motorcycles and from the many reviews I have seen, they all speak of BMW as the best, so I just wanted to have a look. Was very impressed with the bikes...
