That E Class looks pretty tidy. Higher mileage and spec probably the reason for the price.
Significantly roomier than the C Class though, so compare the two before you commit
Yeah - I've convinced myself that the C class will be big enough for 99.9% of my uses. Might even be able to get a C36GET in the back should the need arise. The extra room in the E class may come in handy for the other 0.1% of the time, but I've done 5 up in a 1982 Cavalier 1.8SRi to northern Poland and back before so the C class has got to be better than that.
I'll probably take a look at the E class first, and then make a decision on whether I want to pay nearly double for a 2016 C350E, or stick with one of the cheaper 2009-2012 C180/200's. It's just a bit of a pain in the 'arris that there aren't any closer to the south west - they all seem to be in London or Birmingham.
