I've had the 225 Hybrid GT for two years. Super car if you have, say, solar panels on the roof and charge from a socket — with a 10–15 km commute you drive on electricity for next to nothing. On the motorway at 140 km/h it uses about 6.0–6.3 l/100 km, superb comfort and quietness — and that stylish look!!!

Mercedes CLA Coupe

The Mercedes CLA Coupe cuts a rakish silhouette that blends sporty coupe lines with everyday practicality, giving style-minded buyers a premium image without shouting. Inside it feels more luxurious than its size suggests, with a slick cabin, intuitive tech and a composed ride — the kind of car that parties in the city and still shows up polished on Sunday morning.
