another popular strategy is to get the kbb for the car stock, and then you add the extras on yourself......so maybe you charge an extra 1500$ bucks for all those mods (just ballparking).....you are getting some of your $$ back, and somebody who wants mods (like i did when i bought mine) gets what they wanted.

 

If keeping modded, go for private sale.

If selling to dealership, go back to stock and sell the mods here on EvoM
