Although I'm sad about it, I'm thinking about selling my RS7. I looked on Kelly Blue Book and Edmunds.com to get an estimate on sale price and they don't even have my exact car listed! I guess since it's so new (2017 model year) and the Performance version which wasn't even listed on their websites.

Please help me determine a fair sale price -- Obviously I'm going to lose a lot in 1st year depreciation - I know that. But I just don't know how much to ask.
I'm trying to get help with the sales price before I post it in the classifieds section.
