I'm really interested in buying a 2000 audi S4 Bi-turbo quattro i found. I think it looks sweet has a 6-speed manual, all wheel drive, heated leather seats, climate control, and of course a 2.7 V6 twin-turbo. Stock it has 250 hp but this one is APR chipped so its making 317 hp. I read stock quarter mile times are around 14.3 so this one sounds like it will run in the 13's. I'm just wondering if anybody knows if they're reliable. This one is $13,990. I do know that fixing them is ridiculous cost but oh well any imput is welcome.. Thanks guys
