Audi lent us a 2007 A8, the short-wheelbase model instead of the extended A8 L version. Our Quartz Gray Metallic test sample cost $69,620 including the $720 destination charge, a fair sum for a 350-horsepower luxury sedan with all-wheel drive and a gorgeous Amaretto interior. Though expensive, we highly recommend the $6,300 Bang & Olufsen audio system, the $4,000 sport package with adaptive air suspension and 20-inch wheels (our car wore winter rubber on smaller 19-inch rims), and the $1,500 Alcantara Package. Other goodies included the $4,000 premium package, $600 for dual-zone rear seat climate control, and $550 for Sirius satellite radio for a total of $86,970.
