I'm thinking about buying an Audi equipped with the Quattro 4WD system, and I would like to know how reliable it is with a few miles on it, what sort of problems do you get? How expensive can it get?
I'm asking not only from an owners perspective, but from a mechanics perspective, because I'am my mechanic! I don't have a lot of experience of Audis though, and if I'm going to own one, I'd better know what I'm potentially letting myself in for!
