My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.

With all the features it offers at that price, the MG has no competition. A BMW X1 of similar dimensions with a few extra upgrades costs more than twice as much, and considering that 40% of MG’s spare parts come from Germany (Bosch, Continental, etc.), I’d go for the MG ZS Hybrid without a second thought.
