Mercedes-Benz GLC-Class 2018
The 2018 GLC-Class diesel is a well-built premium SUV with solid engineering, but diesel powertrains from this era face common fuel system and emissions control issues. Ownership costs are moderate for an independent garage, though parts remain expensive. Fuel economy is respectable but not exceptional compared to petrol variants.
