2006 Audi A6 3.2 quattro 4dr Sedan AWD (3.1L 6cyl 6A)
I only had my A6 for 3 months. On the way home from the dealership (It was 5 hours away), the transmission went out. Only an Audi dealer can replace it, so it was a little over $5,000. Then the passenger seat switch broke. It was going to cost $300 to fix, but decided to leave it alone. Then a coolant pipe broke and costed $85 for the pipe plus $25 for the coolant you HAVE to use on Audis. Two days later I got a warning light and took it to the dealership. They adjusted some sensors but warned that a $11,000 repair was about a year away and recommended I traded it in, so I did. I only had the car for 4,000 miles. I am the worlds biggest Audi fan, but if you have to have one, buy one new.

Reliability. I thought a german-engineered car would be better. It has to be hooked up to Audi's special computer to do anything at all. Cheapest labor rate I could find at a dealership was $98 an hour. Parts have to be ordered from Germany which take awhile.
