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.

I took the car for a test drive. I was impressed by the handling, the trunk, the interior space — huge compared with other cars — and the equipment. I’ve been driving Toyotas for 43 years and am impressed by their reliability. Ultimately, the warranty Toyota offers on the bZ4X completely convinced me.
