Firstly, this is a good way to lose a lot of money. Trade price for the car is about £13,000 and you probably paid about £35,000 new. So that's more than £5,500 a year down the drain in depreciation alone. I'd hang onto to it for at least another couple of years to better amortise the original cost. But if you want (and can afford) to change, you might as well look at the current model W212 E Class: www.honestjohn.co.uk/carbycar/mercedes-benz/e-clas.../
