2002 Audi A6 3.0 quattro AWD 4dr Sedan (3.0L 6cyl 5A)
Attractive design wrapped around a nightmare of ongoing expensive repair bills for items I have NEVER had break on any other car I have ever owned! Keeping up with regular maintenance does not help avert the $1500 to $2000 bi-monthly repair bills that begin when the car hits around 75K miles. This has convinced me to NEVER buy another Audi - good looks and style are not worth much when you frequently get stranded on the roadside with a dead car and have to face towing cost AND a couple of thousand dollars of repairs. Not worth the premium I paid for poorly engineered mechanics :-(
NONE - anything I liked about the car has been overshadowed by the constant headache of repairs and break downs. Would sell it today if I could but given this make/model's reputation - it is difficult to find a buyer.
