Not known to be very reliable and requires a second mortgage to afford its service/repair bills. With that said, I’m strangely attracted to it. This is one of the cleanest A6 Allroad I’ve ever seen on the used market- 1-owner and 62K original miles. Well appointed with leather, wood trim, height adjustable suspension, front and rear heated seats and all this back in 2001. Plus it has a very tunable 2.7 twin turbo V6 that’s also found in the same era S4 but in a lifted wagon body.
