This car is probably the best I have ever had to deal with. Unlike Chryslers, Volkswagens (you'd think they were the same, but they're not), GM, and Acura (which are quite reliable too), this car has run like a Mack truck practically, performed beyond belief, and given me a solid 22 mpg out of a full-size luxury sedan. The grip is tenacious for a 4057 lb. car and enables the driver to make quick lane changes if need be (Columbus traffic isn't the most forgiving). All in all, this car is a keeper.
Bought the car certified-preowned, (used). Car was in a front end/rear end collision so price was lower than listed. In spite of the collision history, body panel fit is excellent. Things that have gone wrong...whoever put the drain system for the moonroof in did so incorrectly causing a leak when it rained, the dealer took three trys to get it fixed. Other than that MAP air sensor, trans filter service and power steering fluid leak repair. Above and regular maintenance is all that I've had to have done to the vehicle. Out of warranty so sought out non-dealer service which halved the cost of repairs.
I purchased an A8L and I am very pleased. You never see a lot of A8 s on the road so your A8 stands out at being different. The cabin is so quiet that when you go through the brushless car wash and the dryers turn on you hear the fan motors instead of the wind noise.I sold a Porsche 911 for the A8 and I am very surprised with the performance. The off the line acceleration is very quick and smooth as it holds you back in the seat through all of the gears. My buddies have 745s, and Lexus 430s and they prefer to take the A8 the very few times we get together. Last but not least the build quality is Impressive because the car is all aluminium and straight as a arrow, seams, and door jams.
Over the past three years, it seems like my A8L has been in the shop as much as in the garage. Fortunately, it was Certified, so except for the $50 deductible and inconvenience, it has been relatively painless. Here is a listing of problems: Thermostat (replaced along with timing belt @ 50K miles), vacuum hoses/connectors, Torque converter/Transmission (required replacement), peeling console material, etc. etc. etc....
