I've just got rid of a C32 AMG, after having enough of 250 miles between refills. Bought myself a E320 CDI. I thought it seemed pretty good for it's 173000 miles on the test drive. But now after a week of driving, I really can't believe how great this car is. It is making me think, IF I'd known about this car when looking for the AMG, I would have bought the E class without a doubt. It's incredible. Fast, frugal and super comfortable. Huge boot and a super cruiser. I am over the moon with it.
There's quite a step up from C's to E's in terms of tech, refinement, cabin materials, etc. For what I want in a car they're great.
