Which spec on a Mercedes GLC to go for?

I'm buying a Mercedes GLC 220 d AMG Line with 20-inch wheels. Are they comfortable enough? They look good with aluminium side skirts. Or am I better getting the 19-inch wheels without side skirt? Also I'm getting the light-grey leather and I have been told it has been coated with a leather product to protect the seats; is this true?

Hi Martin,

There's no doubt that the 20-inch wheels and their lower-profile tyres come with a compromise to ride comfort – assuming the car isn't on air suspension. But it might be a compromise you're willing to make for the style. Bear in mind that it is easier to kerb bigger wheels, generally, and that the tyres are likely to be costlier as well. I recommend you test drive examples of both for yourself to make the call.

And yes, Mercedes leather is treated at the factory with a polymer finish to help with wear, tear and staining.
