While not completely related, the owner of a local Audi shop is selling his 2013 S6 for around $46k if anyone is looking. It’s Havana Black (I think that’s what it’s called) with 39k miles, and warranty through the end of the year. It’s fully loaded except the BO sound system. Black sport interior, and one of the wood trims. It currently has a full AWE touring exhaust, AWE intake, bronze 20" HRE FF01 wheels, and some type of drop links for lowering.
He’d go lower on the price without the mods. He’s also an AWE, APR, Eurocode, and 034 dealer if you wanted a deal on additional parts or tuning. He just picked up one of the 5 Viper Green exclusive S3’s, and he’s looking to sell the S6.
