The Tonale is bigger, more powerful, better-looking, and has a nicer, more spacious interior. I’ve driven both — the Toyota is bland and scentless, and simply a poorer drive.

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.
