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.

Nissan Leaf

The Nissan Leaf is a practical, easygoing electric hatch that turns daily commutes into a quiet, effortless affair while offering more cabin space than it lets on. It’s a sensible, wallet-friendly step into electrification for buyers who value comfort and simplicity over sporty drama, though those chasing long-distance thrills might look elsewhere.

The author of this comparison probably doesn't read what they're writing. Almost 100 Nm is a small difference? XD And by the way, the Leaf is listed at 6.9 s to the first 100 km/h while the rival is over 8 s — that's not a small difference… it's a shame to read this comparison with so many mistakes; better to take a drive and judge for yourself.
