Which used Mercedes GLC estate should I buy?
Of the pre-facelift cars, the 168bhp, 2.1-litre, 220d diesel pulls well enough, although the gutsier 201bhp 250d can accelerate up to speed quickly in a more relaxed fashion, so is worth paying the small premium for. The 350d is smooth, but it's expensive to run and emits a lot more CO2 than the 220d and 250d.
The GLC 43 4Matic, GLC 63 and 63 S are range-topping turbocharged V8 models are ballistically fast and good fun to drive. But you will have to pay the price for that, with much higher running costs.
