Swathed in luscious Amaretto Valcona leather, dressed in gorgeous Sycamore wood trim, decked out with plush Alcantara door inserts and headliner trim, and accented with real aluminum, the Audi A8 is a treat for the senses. Pliable materials cover the dash and doors, and every piece of switchgear features the heft and damping appropriate to an expensive automobile. Even the few hard plastic surfaces feature pleasing tactile and visual qualities. The Audi A8 is a work of art, with the single exception of the silver plastic trim that, if it were coming loose, would look just like the stuff Chevy installs inside a Cobalt SS.
