Besides a German-bred V10 under its hood, the all-wheel-drive 2007 Audi S6 packs a bounty of standard features behind its $74,020 base price (including a $720 destination charge and $1,300 gas guzzler tax). As befitting a pricey luxury car, there’s a leather-wrapped power tilt and telescoping steering wheel with memory, a power sunroof, a dual-zone climate control system to keep the driver and front passenger comfy, high-grade Nappa leather on the seats and door panels, power front buckets with memory for the driver, and a tire pressure monitoring system.
