Intuitive to operate, excellent tactile feel, high seating position. More range or a larger battery would be desirable, but that would be nitpicking at the highest level.

Delightful driver's car. Light-footed, quick, silent and sporty.
If the range could be improved, it would be absolutely top.
You do have to buy a few option packs to make it fun — expect to pay around 70 grand.

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.
