Just sold my w212 Mercedes estate 2010 . It was a petrol 1.8 turbo 250CGI . I paid £12000 4 years ago with 46000 miles on it . Sold it for £11000 with 78000 miles on it . Full Mercedes history . I could not believe it until I saw there were no other petrol Mercedes E class on autotrader or eBay ! Still pretty much depreciation proof driving for 4 years .
