Have had the S4 now for just over a year and am contemplating selling it, its a fantastic car and does all I want it to do, but getting itchy feet and fancy a change. Have always sold my cars privately (really dont have the patience for car salesman offering you £100 and a bag of sweets in exchange for your pride and joy), as much as I know I will never get anywhere near my money back (£21k), nor do I expect to, question is whats it worth?? Am the 2nd owner, 43k miles, all the toys as in my signature, immaculate condition. Thoughts??
