2001 Audi A6 2.7T Quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)
I wrote a very positive earlier review about how reliable the car was after 6 years of ownership. It must have jinxed me. Since then I've had an $1100 alternator replacement, a frozen front caliper and a broken right front coil spring (the day before I was to trade it in!) I bought a new 2009 Ford Fusion SEL AWD with nav, leather, heated seats, alloy wheels, rear backup sensor, Microsoft Sync, etc for 1/2 the price of a new A6. A close friend of mine who has the same car just spent $4000 in repairs on his 2001 A6.
Extend the new car total warranty to 100,000 miles!
