Part 1: After 8! Have tried cars, the current vehicles showed despite very careful handling are not usable. Average keeps the wind-up 10 retreats stand, then is Sense. Either speculating on many Stupid acquire the replacement engine or intressiert anyone resending the buyer and (as we did) then give up in exasperation. A great pity, because in my childhood I know how much fun can make the system. But even I Rowdie had never managed to demolish a car.
Part 2: On request SIMM Marketing admitted that there were manufacturing errors. Unceremoniously new engines were sent home free us. These have the old quality.
Conclusion: Darda is still purchasable, if you caught a defective car, turn you, with the batch number directly to the distribution of SIMM Marketing.
