Thinking of selling

I have a very,clean  B7 S4 Avant 2007. I am the original owner.I have different needs these days and “may” sell the car in the next 6 months. When I talk to the dealer(s) regarding trade in the conversation is always a short one! (And I’m thinking about ordering an S6).–I’m trying to fiqure out the value of the car and the market. Any guesses would be appreciated.

White on Black, 6 speed manual.Stasis-coil-overs,exhaust,sway bars. Carbonio air intake,Evo tech computer upgrade (right at 400 hp)lowered,Hartman A5 wheels,with new Michelin Pilot super sports–also have original wheels with Blizzacks currently mounted.Always garaged–Just over 40K miles.-The car is without a dent,ding or paint chip.Never crashed and running perfectly!

 

Thanks,
