The Peugeot 508 turns heads with a low-slung, almost coupe-like silhouette and a cabin that feels grown-up and surprisingly premium for the money. On the road it balances comfort and poise with a playful edge, making it a convincing choice for buyers who want something stylish and sensible without shouting for attention.

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!!!

Mazda 3 Sedan

The Mazda 3 Sedan dresses like a compact premium car, with sculpted lines and an interior that punches well above its class. It rewards drivers with eager handling and a composed, comfortable ride that turns routine runs into something a bit more enjoyable — proof that style and substance can share the same key.
