Hi any help appreciated. I am thinking of buying a Second Hand Diesel E Class 2010-2013 approx, and am wondering whether to opt for a E250 or E350. My motivations for buying is for a long commute to work and safety. I am aware there will be differences in insurance, fuel economy and considering cost of repair etc. However I am really interested to know what people would opt for if they had to choose between the two? TIA
