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!!!
