They are very knowledgeable about BMWs; they are true enthusiasts, having track support programs and taking their own cars to tracks days. Therefore I trust them to repair and prep my car for both street and occasional AutoX events. I met with Derek, who kept me updated on the progress of the repair and sent me photos. They are open minded about modifications and DIYers asking all sorts of questions. If you have a project car, they are a great shop to build relationships with.
