I bought my '07 A8L a year ago at Tyson's Audi in Virginia. It had 61,000 miles on it and although it looked practically showroom new in every way, I was a bit worried about spending serious money on a 4-yr old car with that many miles. My worries have been laid to rest 20K miles later. I have owned 4 BMW's (7, 5, and 3 Series) and one Benz. I never liked the Benz but loved all of my BMW's and never thought I could appreciate a car more than a BMW. The 1st time I laid eyes on this car I fell in love with the looks. Mechanically, fit & finish and handling, this is the Ubermachine from Germany. Simple as that. No use enumerating it all. Enough said. I'm in love.
Bought a preowned A8L '07 a couple of years ago. Have put 70K on car since. It has been remarkably reliable. The build quality is excellent. I don't get the gas mileage it promised unless driving over 70. I have all service done at dealership, and have been very surprised at the low cost of maintenance, and the quality of service. Had a new A4 in '07, hated it, swore I'd never buy Audi again, got bad service. Bought the 8 because I needed big and 4WD. Expected many of the same problems I had with the 4, but it is a much better car. And I think Audi is a much better car maker and has made huge efforts to improve customer satisfaction.
I've had the privilege of owning/leasing BMW's ( 5 series ) a couple of 911's and a Mercedes S class and I have to say that this A8 is tops for performance, class, reliability and most of all individuality. In LA there are thousands of S Class and 7 series. I can honestly say I've not seen one other dark blue short wheelbase A8 with the performance 20" wheels in 3 years of driving here. The car is special in every way. The handling for a large sedan is spectacular due to the aluminum body and quattro. The fit and finish inside of the amaretto interior are awesome. Power is smooth and refined. Great Bose system. Biggest issue will be whether or not to buy it after the lease! Not one problem
Finally retired my 8 a few months ago. Absolutely beautiful car. Loved driving it. And still miss it greatly. The expense of repairs quickly exceeded the residual value of the car. The car was very reliable and honestly the issues that I had with it were worn part maintenance issues. But items like the suspension repairs @110K for $7400. Other small issues for another $7500 soon followed. $15K for a car I then traded for $12K. But I did get a new S7 so obviously I still think they are great cars. Really had no problems at all until 100K. I don't really think Audi's are that expensive to maintain, either, nothing like Porsche or BMW in my experience.
This car has it all. Looks, performance and there are not many on the road. Every other car in LA is a 7 series or S550. This is one amazing car. Tight , great motor, short wheelbase handles great. Bose stereo is more than adequate.
