@ Admin: I'm from The Netherlands.
The smart forfour is based on the Mitsubishi Colt (Xiali Toyota Vizi size) and the car is on the highway sporty and not noisy. The car is also really spacious and has an economic three cylinder engine with 55 kW/75 HP.
The smart forfour and the Mitsubishi Colt are both built in the NedCar assembly plant, but the production of the forfour ended because of the low sales (59.100 in 2004 and 43.700 in 2005).
