  • Coulter Dean


    Coulter Dean had Mporium in mind for over a decade prior to its formation. Working through various performance shops to build experience, he dismantled M3's on the side and trained in their assembly and repair, while also building several fully modified M3's for himself over the years with an OEM PLUS type feel. Coulter maintains an above average skill set in the shop environment from advanced repair and tuning to fabrication and machining.

    He works in the shop alongside head tech Mike Holtmeier, who is a BMW certified master technician with years of dealership experience and training. With a background in heavy duty diesel, he is distinctly aware that jobs must be completed correctly the first time. Together, the Mporium team exists to produce a 5 star experience no matter the type of BMW serviced.


  • They really know their stuff, they are committed and are very reasonably priced. Definitely recommend them for any BMW related work!

  • Great speedy service, I highly recommend for anyone with a M Series BMW! I was kept in the loop the entire process which made me very happy. Rod bearings and DCT all in one day. I’m very satisfied with the customer service I received through out! 5 stars hands down!

  • Coulter and Mike truly treated my car like their own. Excellent workmanship, attention to detail, fantastic communication and fair pricing. I can't recommend them highly enough!

  • Coulter is the man. Quoted me much, much less than other independent shops out there for a valve adjustment and for sure much less than the dealership. Had me in and out on the same day as well. I liked that he sent pictures of the work as he was doing it. I'm glad I found a trustworthy guy I can rely on for my M3 and won't hesitate to go to him for any future work.

  • As always Coulter came through and saved the day. He took the time out of his busy shop schedule to keep me running today. Thanks man!

  • These guys were my last option to get my exhaust pieces married together. I had taken my car to multiple shops and no one could do it for one reason or another (car was too low, car was modified, no one could do the welds, etc). If these guys couldn't do it then I was prepared to just sell off my exhaust and get something new. Luckily they were able to work their magic and their work is PHENOMENAL! All the welds look super clean and even cleaned up my car afterwards. Highly recommend you taking your M's to these guys especially if you're in the north side of the Dallas metroplex. Thanks guys!

  • Service exceeded my expectation. Short turn around time with quality work. Mr. Coulter is very knowledgeable and knows what he is doing. I'd highly recommend Mporium and will be a returning customer.

  • Awesome job, awesome price, awesome timing, couldn't have asked for any better!

  • Have bought e90 M3 full interiors from Coulter twice now. Both sets were shipped to Miami on two separate occasions. Coulter packages the pieces to perfection better than I could ever hope to do myself. Both sets got to me perfect and in great condition. You can tell when someone takes pride in what they do by just how the treat the things that they sell. Thanks again really appreciate it.

  • Awesome guy, pleasure to do business with and very knowledgeable in his craft. Definitely a person/shop to check out.

  • Mporium has done an amazing job with e92 M3 so far. From getting my supercharger to run correctly, to a full motor swap (by choice not blown up lol), to maintenance items everything has been doing quickly and correctly with excellent communication each time. Highly recommend this shop to anyone who wants top quality work and customer service.

  • I did a lot of research before I chose this place to take care of my Bimmer. I was not disappointed that I did either. Coulter is a fantastic guy and runs a great shop. The mechanic is a master mechanic from classic and really knows what he is doing. The repairs were very quick and the prices were even more fair. I was not expecting this level of service when I took my car in, even with the perfect rating. I was pleasantly surprised. I will be taking my car here for any repairs in the future.

    Very highly recommended.

  • I've had my car for 16 years and haven't trusted other shops to work on it until I met Coulter and Mike. They did a fantastic job on my mismatched exhaust including a lot of custom fabrication with impeccable attention to detail. I can truly say that they treated my car like they would their own and can't recommend them highly enough!

  • Extremely happy with the work Coulter did on my M3. Rod bearing job was done right, fast, and at a very reasonable price. They even cleaned my oil pan and belly pan before re-installation - little things that only an enthusiast/owner would do! Photo documentation of the entire process was also superb.
    Its hard to find a shop that knows these cars like the back of their hand and Mporium team is extremely knowledgeable. And they fix things the right way - no shortcuts taken. Very highly recommended ///M-shop in DFW area.

  • Coulter is the guy to go to if you have an M car in the DFW area. Fair prices, fast work, and great results. You can tell he's passionate about what he does. Also sends pictures showing you the progression of the repair as well which is a nice touch.

  • Great small shop, personal service and very trustworthy. I’ve been in the metroplex for almost 5 years I and only just recently found Mporium... wish I’d found them sooner. If I had, I would have kept other M cars I had that I’d decided to get rid of, since I hadn’t been able to find a shop I could trust. Maybe I’ll be in the market for another M car soon again now.

  • Took in my 2013 M3 in for various maintenance requests as he has been highly recommended. I can tell you that Coulter delivers on all counts. Not only was he flexible with the pickup and drop off times but he luckily found some additional issues needing repair and documented via pictures how he found them. He is extremely knowledgeable with BMW M cars and explained things about my car and its history that I never picked up on. I can't recommend him enough, especially for BMW M cars.

  • I used to be a mechanic and still enjoy turning wrenches every once in a while. However, the rod bearing job on the S65 engine is not a home garage type of job I was interested in tackling myself. Plus, I just simply don't have time these days. So, I purchased the parts and started searching for someone that had knowledge of these cars and had done this job before.

    It came down to a few different BMW "specialty" shops. Most of which tried to talk me out of doing it, weren't local, wouldn't call back, or didn't have any clue what they were talking about.

    When you buy an M car, there is an enthusiast level of perfection that one seeks. It is unheard of to find someone that has that same enthusiast level for YOUR car when you bring it in to have work done. That is, until I met Coulter at MPorium.

    After having the rod bearings and motor mounts changed, it feels better than the day I bought it. The shifting in the DCT is crisp and precise and the front end just feels solid.

    Coulter over at MPorium seems to know these cars like the back of his hand. He was honest and patient to explain the job. The cherry on top, is he is fairly priced. Especially, for the quality of workmanship and the quick turn around. Heck, he even said I didn't have to go through the headache of purchasing all the parts because they stock the BE Bearings and ARP bolt kits in house! They are literally a one stop shop if you need to have this done!

    Attached are the photos of the rod bearings that came out of my 2011 E92 M3. The car had 83,400 miles on it and no symptoms. If you haven't looked into getting this critical preventative job done, you need to call Coulter. It isn't worth the risk of what could happen if you ignore it.

    A special thanks to Coulter over at MPorium! You rock!

  • Coulter with Mporium BMW took care of rod bearings, engine mounts, and an oil change for my 2011 M3. He knows the cars inside and out, and went the extra mile tracing down some electrical issues, keeping me informed of his progress.

    Coulter and the team are great with e9XM platform and can’t stress enough how much help they are. Took my e90M for Rod bearings and in the process they found deficiencies from previous repairs. They fixed what they could with the timeframe I had, coming from out of town. Wish I lived closer to the shop so they can manage most of my repairs. 100% recommend their service for all BMW repairs.

  • Marcus B.11 months ago

    This place was recommended to me by members from the N Texas BMW Facebook group and local members from a online BMW Forum. I needed repairs to my F15 X5 xDrive 50i air suspension. I am happy to report that the owner, Coulter has been an absolute pleasure to work with! He communicates and keept me informed of all progress and estimates for repairs. As a Small Business Owner myself, I truly appreciate good communication! They even fixed a minor but annoying chime caused from a loose lower body trim panel. Most importantly, they fixed the issue at a reasonable and fair price. I would not hesitate to return for additional repairs or service and I highly recommend M Porium due to having Master BMW Technicians on hand doing the work. - Marcus B.

    Absolute professionals. Everyone there as a real enthusiast. I did a lot of searching and found these gentlemen at the suggestion of bmwcca members and some forums. After a 450mile trip from New Mexico to McKinney, I knew I was in the right place the moment i walked into the lounge. They were very honest and accommodating my need for a one day turn around. They even gave me a discount on some labor rate as well. This is THE place to go for bmw maintenance or repair. Can’t recommend them enough! Ps: get your rod bearings replaced. I saved my motor!

  • Israel Contreras9 months ago

    Always top notch service and commitment to quality work. Technicians are very detailed oriented and knowledgeable. Personally live a few hours away from the shop but will gladly drive every time for the peace of mind that the job will be done right. I’ve had major services done from rod bearings to jobs as small as oil changes. They take photos of the job as it is being completed and compile them at the end for your personal record and theirs. I would 100% recommend MPORIUM BMW.

  • Georgi Novakov8 months ago

    I recently had a replacement/retrofitting and electrical wiring installation and modifications performed on my vehicle at Mporium. Coulter did a stellar job. Extremely knowledgeable, with the highest possible professional expertise. Wonderful customer service as well, nice and accommodating. Their BMW dedicated service shop is indeed a real gem in the entire DFW area. Rates are definitely unbeatable if compared with BMW dealers.

    The staff at Mporium have always given the best balance of service and price. Trust is so important when it comes to having your car serviced and I would trust any of my cars to be serviced there. The level of communication is also superior to what I’ve experienced at other “specialty” shops. Would recommend Mporium to anyone.

    We learned about Mporium during the search for our BMW. They did the pre purchase inspection on our X5M before we bought it and we've taken it to them ever since. We really like how they treat the car as if it was their own. They always send the estimate and status to our phone with pictures of the job... Totally stress free. Customers for life!
