2004 Audi A8 L quattro AWD 4dr Sedan (4.2L 8cyl 6A)
Most of the reliability issues owners have experienced are electronic problems. Interestingly, I have had major mechanical issues - transmission, suspension, cooling system and more. All these problems started right around 51K miles, just out of warranty! So far I have spent over $6,000 in repairs. About $4,500 of that is parts, because you won't find aftermarket parts for this car. If you are reading this review you are probably considering purchasing a used 2004. My best advice would be to get the best extended warranty you can. Get a warranty that has "stated exclusions" only, so you know exactly what will not be covered. With all that said, I really do love driving the car!
Top notch interior finishes, comfort, style, luxury features, all wheel drive. I really love this car when it's not in the shop!
Reliability, which I've read is greatly improved in recent years.
