Audi's flagship is completely revamped and sports a lighter chassis, more powerful V8 and a treasure trove of comfort, safety and suspension upgrades.

Edmunds says

This fast and comfortable premium luxury sedan easily holds its own against more expensive competitors.

Love Hate Relationship

PFraser, 12/10/2008

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 …

Expensive Unreliability

Lynne LeGallais, 11/10/2009

2004 Audi A8 L quattro AWD 4dr Sedan (4.2L 8cyl 6A)

We expected Audi quality and attn to customer service when we purchased this vehicle. Our experience has been terrible. Mechanical car repairs since 80,000KM have exceeded $7,500. Examples of necessary repairs are, replacing starter cost $992.16, dysfunctional remote which has had batteries replaced 5 times. Four upper control link bushings cost $1130.53, breather valve atop manifold …

It even gets remarkably good gas mileage (25 mpg on the highway at 72 mph) thanks to its aluminum body and consequent light weight. What's the catch? It's had to be …

Heartache/headache

2004 Audi A8 L quattro AWD 4dr Sedan (4.2L 8cyl 6A)

This car is so comfortable we call it the sofa. It has,however, been a maintenance nightmare. It is constantly in the shop and dealers in northern California uniformly provide lousy but expensive service. When the heater failed while in Minnesota on a winter trip, the dealer groaned when he saw it was a 2004. Nothing but headaches, he told me. Tons of electrical problems to start with, …
