Our Audi A8 exhibited better build quality than a recent S4 Cabriolet test car, but there were still a couple of flaws that needed addressing before the dealer could command $86,000 for the car. On the outside, the rocker panel trim on the left side did not create a flush joint with the driver's door, there was a noticeable difference in gap tolerances for the rear doors, and the greenhouse trim at the left C-pillar was loose. Inside, the wood panels covering the MMI display and the ashtray were mounted off-center, and the Alcantara-trimmed sunroof cover was sticky and difficult to pull closed.
