2002 Audi A4 3.0 quattro AWD 4dr Sedan (3.0L 6cyl 6M)
In my 30+ years of driving, I've owned Corvairs and AMC products that would be considered "problem cars", but nothing matches the unreliability of an Audi. I purchased both a 2001 and 2002 A4 and have become very familiar with the local wrecker companies. The 2002 is now having it's 4th engine installed (after only 50,000 miles). The stereo system has been replaced three times. We traded in the 2001 at a loss after being towed three times for coil issues. Stay away from Audi! This is the worst car I've ever owned, including the 1964 Corvair I paid $100 for in 1974!
