Personally I like the current more aggressive look of the C-class now than the upcoming C-class. If I was in the market for a regular Merc, I'd wait for the new C and then buy the old C on the cheap. I don't buy cars for resale value, so that factors little in my mind. I suspect though, that when the new C comes out, to get a well loaded one you're probably going to be into the current E prices. By that light, if you need space in the back, it may be better to wait for 2015 and buy a 2014 E on the cheap.
