2001 Audi A6 4.2 Quattro AWD 4dr Sedan (4.2L 8cyl 5A)
I purchased my A6 4.2 from an Audi dealership, If there are any reliability issues I am going to assume they are already taken care of, the car is quick, fun to drive and is not afraid in bad weather even with 300 ponies going to the ground (thank you quattro) my best advice, see if they have service records on the car you wish to purchase, and ask them what was done to the car before they put in on the lot. The dealership I bought mine from spent about 1800 dollars in the shop correcting a few problems associated with most Audis. I have owned a lot of cars, this one is fun and a great value for a luxury sedan (thousands less than BMW or Mercedes)
Quattro, 4.2 engine, sport package looks, and interior layout.
those silly cupholders, I am glad they moved them in 2005.
