For me incomprehensible reasons Darda tracks are unfortunately came a bit out of fashion. Although set in terms of durability and playing fun any Mattel Hot Wheel track loosely in the shade. Today, the little runabout to amaze with her incredible drive still - and finally without batteries and artificial sounds. The track contained herein with 4 loops creates loose the vehicle. The parts contained quite a lot of variations can be created. However, in order to increase the fun I absolutely recommend 1 or 2 more vehicles. Who is toying with an additional rail 50146 Speedmaster very well served by the Darda, as both tracks complement each other perfectly because of the different web parts and can be combined. You might be just a couple of straight rails to buy and use them as a ramp for Matchbox cars without drives (eg from the high bed from start). My son can determine spend hours, come what vehicles from its fleet most.
