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.

Ferrari SF90 Roadster

The SF90 Spider is Ferrari's drop-top flagship, blending blistering hybrid performance with an intoxicating exhaust note and race-bred agility wrapped in theatrical Italian styling. It's shockingly usable for a hypercar, equally at home carving country roads or turning heads at the valet, and it will leave you grinning like you just skipped a very responsible meeting.
