My history with selling or part ex'ing will just show how much dealers wind up their resale price.My passat sport that i found on Volkswagens uk used car search price for £19250 in november. was an 07 with 11000 miles on the clock. ive just sold the car back to the same dealer.The only things ive added to the car were a 2nd hand £300 mfd2 cd rom sat nav, multifuntion steering wheel and ipod prep. Put 2500 more miles on the clock to 13500 and they have got the car on the forecourt for £20495!!!!. Just goes to show i added some xtra's and Vw dealer ramp up the cost! :
