The GLE is much bigger than the GLC. I’m not an SUV fan but I do like our GLC220. It’s got the 2.1 turbo diesel engine (as has the 250d, just with more power) and enough performance for every day driving. The nine speed auto box is excellent and we get around 35,000 miles on a set of tyres.
Ours is a 68 plate and goes an average of 45mpg. Overall we have no complaints.
We had a 2010 ML300 a while back and it was bigger, heavier and much more expensive to run.
