We took our '02 325i there a couple of times to get some cooling system work done (hoses, expansion tank, radiator) and they did a decent job. I don't think their prices were that much less than the dealer, but it was right down the street so it was close. One of the guys at the front desk kind of has an attitude (dan or dave). They had a BMW Master Tech, so I felt confident taking the car there. Not sure what VW/Audi training they have.
Why not just go to Lindsay?
