I drove the Toyota RAV4 and the Kia Sportage on business — the Kia’s engine and automatic gearbox are much better. It doesn’t jerk or scream, and the shifts are smooth. Comfort in both cars is very similar.

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.
