I'm in the UK and looking at either C180K (petrol) or C220D (diesel) estates. Probably automatic. The performance of both is very similar, and although the diesel is more economical it costs almost £3000 more, so may not end up cheaper overall. The C220 might retain more of it's value but I'll be doing 90,000 miles in 3 yrs so think the values will be pretty close.
Anyone have any thoughts on the best one to pick?
Thanks
