We've been driving only the B180D automatic for 9 years — there's nothing better. Great on long trips; the next one will be another B180D automatic.

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.

It may not thrill the enthusiast, but its sensible layout, sturdy build and Toyota badge make it a dependable, no-nonsense choice for anyone needing space and reliability rather than flash.
