Because hardly to use the bad cars - train actually ok.

The train was a gift for the fourth birthday of our son. The value for money with respect to the "tracks" is not objectionable. The robust plastic is basically indestructible and easy to set up for children.

Since the vehicles but still (as of October 2014) have the quality defects already widely described, the web is hard to use.

The included in this basic setting claret sports car works reasonably. If you "to the stop" rears him - what is given the poor processing hardly dares - he creates - sometimes - with sorrow and distress one full round with two loops, nearly 7 meters distance. However, not if you build the track as in the picture by incorporating the two long, yellow rail sections as flexible loops and built the red curves as steep turns. Then the vehicle is not even manage one of the two loops, the apex of the first loops he falls down due to lack of momentum, no matter where you start the vehicle. The two long, flexible yellow rails so you can take just as long start / finish line, so the car can get enough momentum to overcome the two small loops.

I had from the beginning some additional tracks and - bought loops to have a slightly larger car. For what and whom this expansion sets offered, however not obvious to me. Since the vehicles - if they work at all - create with difficulty the base path, perhaps another small loop (but rarely), you can save more rails or even spectacular loops, because the create not currently shipping vehicles with safety.

The vehicles are on the one hand for the weak engine - if it works at all - too heavy, so that it is not enough and not long enough to receive energy, on the other hand easily because not generate enough pressure to stay in curves in the track. It's a mystery to me how one can give such a weak perfomance ever released for sale. Obviously, the quality has completely failed or is non-existent in the company of the manufacturer.

From three additionally acquired silver Porsche Boxster (one was included in addition setting, two I ordered separately), only worked in the additional set, the two separately purchased were defective from the start and went back. The included additional set but did not even make a lap, flying at 50% of trips from the first curve or creates not the second loop.

30 years ago, the quality of the vehicles was significantly better.
