Tires are ContiProContact 245/45R18 XL load that were OEM on the 2012 A6 I got. I estimate 10k on them - $400

DimSport MyGenius for user PCM programming. This only transfers the files and was used with Eurocharged tuning. $250

BlitzSafe AUX adapter. Plugs into OEM radio and provides an AUX headphone jack. I will also include a 6 foot stereo to headphone jack cable. $50
