No Reserve: 1995 Audi S6 5-Speed

A high-performance sedan from the '90s, this 1995 Audi S6 is a rare find. Manufactured in Germany before Audi's acquisition by Volkswagen, it's powered by a potent 2.2L turbocharged inline-five engine, boasting 240 horsepower and 296 lb-ft of torque, mated to a smooth-shifting five-speed manual transmission. Distinctive features include the large BBS alloy wheels, quad exhaust tips, and the iconic S6 badging, all hinting at its sporty nature. Despite being nearly three decades old, this S6 is not reserved for bidding wars; rather, it's open to the highest bidder in the scenic city of Boulder, Colorado.
