Matt and his team provided professional, thorough, and valuable inspection and repair on my BMW. The entire process from dropping off at their beautiful and clean facility, to receiving a detailed inspection report, including pictures and videos, to having the repairs done by a qualified, certified technician that knows about my vehicles specific needs was top notch. They were able to give me a ride home in their courtesy shuttle and even offered me a loaner vehicle. read more

Automotive Dynamics did an awesome job on fixing my issue at a reduced price over the BMW dealer. Highly recommend them and will use again. Very honest and not upselling. read more

I am a professional mechanic with 40+ years of experience. I run a very busy company and recently allowed Automotive Dynamics in Woodstock GA to work on my truck because I am simply too busy to work on my own vehicles any more. The sensor in my fuel tank that runs my fuel level gauge was malfunctioning and needed to be replaced. I made an appointment which required me to wait two weeks into the future. I took my truck in on a Monday and it was promised back by Wednesday. Wednesday afternoon, the owner Matt Braden called me and said he had not worked on my truck because "other work had come in". This was the first insult... why did I make an appointment only to be pushed aside for other work? Matt said he had to remove the fuel tank from my truck to change the pump/sensor assembly. He went on about how hard it was going to be because it was half full of fuel. We calculated the weight of the fuel while on the phone and it was only about 150lbs. With a lift and a transmission jack, this is nothing and very simple to do. There are only 4 bolts and a few hose clamps holding the fuel tank up into the truck. I told him I could wait one more day and he said he would work on it. When I went to pick up the truck, the bill was $755!!! I was SHOCKED. He charged me 4 hours of labor to change the pump/sensor and 1 hour to adjust my parking brake. The parking brake adjustment takes less time than it takes to put air in a tire. I had no idea he was going to charge me more than a few dollars for this. I went to drive off, very upset, and then put the parking brake on to test it. I was able to drive right off with the brake on! It was delivered to me in a completely UNSAFE condition! We had to diagnose this and repair it at my shop. The problem was easy to find. An axle seal had failed and allowed oil to pour into the brakes. The brakes were ruined with no pad material left and simply slipping providing no safety. This should have been alerted to me as it was easy to see without taking anything apart on the truck... the backing plate of the parking brake had oil all over it! This terrible sloppy careless mechanic isn't qualified to even touch a brake system. (see photos) I was driving the truck from GA to TN the same day. While fueling the truck I decided I should inspect the work to make sure my truck was safe. I noticed no one had removed the filler neck to the fuel tank, as all of the clamps had never been touched and had 15 years of dirt and grit on them. How did he remove the fuel tank? I checked the other end of the filler hoses at the tank... same thing... no one touched them. How did he remove the tank? Then I checked the four bolts that hold the tank in. No one had touched them!!! It was 100% clear that no one removed my fuel tank. They LIED IN MY FACE. This truck is a farm truck with a big hole in the bed for a gooseneck hitch. I looked in the hole and you could clearly and easily see the pump. (See photo) It is held in by just 6 small screws. One hose clamp on the fuel line, and one quick couple electrical connector. This pump can be removed and reinstalled in less than 10 minutes!!! How do I know that? There is a Safety Warning Tag on my new pump. The careless sloppy mechanic pinched the tag between the gas tank and the pump leaving an open airgap into my fuel tank and leaving my truck in a DANGEROUS condition!!! I hoped the tag would simply slide out as it was made of plastic, but it had been cut by the pump when it was tightened down. (See photo) In the end, I had to remove the carelessly installed pump myself, find the chopped off piece of tag, remove it from the sealing surface, and reinstall the pump myself. (See photo) Every single thing this terrible shop did had to be undone, and redone correctly by real professional mechanics, at a loss to me. Even worse, this terrible unscrupulous thief charged me 4 hours of labor for the 6 minutes of work it took to change the pump!!! I know because I had to repeat the job. To add insult to injury, they charged me $29 for "Supplies" when NONE where used, no even one penny's worth of chemicals or material were used to DEFECTIVELY assemble my truck and leave it in an UNSAFE and DAMAGED condition! I called the owner Matt the next day, and he admitted he had not removed the fuel tank, as he knew I had caught him red-handed STEALING FROM ME. He said he would refund 100% of my money the same day. I waited for almost 3 weeks, and have never received any refund, so I have file a dispute with American Express to get my money back. I have since had to have the parking brakes completely overhauled in order to make my truck safe. This matter will appear in a lengthy Youtube Video on my Channel, and will be reported to the Better Business Bureau, and other social media outlets in an effort to ensure no other motorists are victims of this horrible operation.

I took my 2001 Porsche 911 Cabriolet to these folks to have a post purchase inspection done. They identified some problem areas and made the repairs in a timely fashion, getting my car back to me for the weekend. Their communication and service is wonderful!! These folks are real Euro Car people and enjoy the work that they do. They treated my wife, son and I very well and even let us tour their shop to see the other awesome cars they are working on which included Maserati's, Rolls, Bentleys, other Porsche's and my favorite a beautiful, red Ferrari. They earned my loyalty and I'm lucky they are right around the corner from us in Woodstock. read more

When we moved to Woodstock EVRYONE said this was the place to go. Well, 4 years later I can tell you, THEY ARE THE BEST! They have been able to diagnose and repair a Mercedes that had been in and out of other shops several times. And they have saved me from going back to the dealer with both of our Porsches. Every person we have spoken with has been extremely knowledgeable and professional. They are top notch and we have had zero issues with any repairs/services. Highly recommend them to anyone with a luxury car in the area. Several of our friends have even driven from out of the area with their vehicles. read more

My PorscheBoxster sat there for weeks,with a cooling leakthat couldn't be diagnosed.They did replace an oil air separator, but unfortunately not installed correctly. We resolved this situation after I had the car repaired at an accredited Porsche shop; "Freed Performance" in Cumming. Auto Dynamics admitted their mistake and settled on a refund.I commend them for that move.It makes feel better about the repair businesses and their honesty in general.I can recommend the folks at Auto Dyanmics but maybe Porsche owners should seek other shops. read more

Since acquiring my Mercedes C300 I have used several locations for service to include a Dealership and a locally-owned European Automotive service specialist. Automotive Dynamics provided the best experience of all of these locations. Their staff is extremely pleasant and the quality of their service is excellent.

If you are thinking about going to the Bentley Dealer - STOP! They were able to fix something on my Continental GT that the dealer stated required the engine out $$$ - Not only was this shop able to do it but at a very great price! Well worth the 1 hour drive to get quality service! Thanks again Matt for everything - DR HOWARD read more

I don't know where to start about telling you how great this company is. I have a 2008 Mercedes CLK that I take to Matt whenever it needs work. Before I found Matt, I had always taken it to RBM of Atlanta. They were good, but they do not compare to this place. The prices are much better here, and they are fast! I trust them and they really do great work? The last time I had work done, Matt actually drove 25 miles and brought the car to me at work. That is going above and beyond and I will never go anywhere else or any car repair! I'm so glad I found this place! read more

Found Matt after he placed his card on my 2012 Audi S4 in a parking lot. Always had the car serviced at Audi North Atlanta but never had the customer service as I have had with Matt. Recently had my rotors and pads replaced and what an awesome experience. He has my business for all my car care needs going forward. read more
