2001 Audi A6 4.2 Quattro AWD 4dr Sedan (4.2L 8cyl 5A)
Bought this used with 78k miles. It's a 2001 4.2 with sport package and all upgrades. First thing I did was do full timing belt service. Not cheap, but good insurance. Car runs great and performance is strong. Previous owner lowered 1.5", so handling is great, but ride is choppy. Hazard light unit failed shortly after buying -- a $300 fix. But with both fingers crossed, I'm very pleased with the car. Around $20k invested in total now. Barring any major service, this is a good value for what you get.
Performance and handling. Interior design and exterior styling (better than the new models IMHO). Value (barring major problems).
