"Took my 2013 c300 in for a weistec ecu tune, best money I ever spent this is how the car should've come from the factory great communication from the staff and great service, I will be coming here for all of my German car needs!"

"I truly appreciate the Guy's at Profi. They really have taken great care of my vehicle, not to mention their prices are very reasonable. They don't try to stick you up like the dealership does and for that I'm very grateful; you guys ROCK!"

"I took my 2011 S4 here for an oil change and transmission gear oil service. Miro is very knowledgeable when it comes to Audi and especially with the s4. I was confident that they would do the job after discussing it with him. Very professional. Profi is going to be the shop that I will take my S4 to work on."

"Had my car in for failed emissions. They tuned it correctly and the car runs smooth. Better then when I brought it in. They also took it to the emissions test for me and it passed. Very satisfied with the service and would recommend them. Easy to work with. Picked up after hours."

"By far the best shop I’ve went to, very professional and the work was awesome, they made my car run like a champ after sitting for about 8 months, and I also recommended the shop to my buddies and they also loved their service. Most definitely recommend them for all your German and domestic car needs."
