This applys to the collectors/runners mostly: Often times when putting our beloved shelf queens back in the display case (or just a car we want to keep the dust off of), the little screw that holds it down to the base turns up missing, gets broken or in the case of the new Mongram cars is not used in leu of tie downs on the wheels. Solution: Take one very powerfull magnate removed from an old broken computer hard drive and tape it to the bottom of the base. Car will stick to base even when upside down and can be carefully removed from the case when needed. Note: I don't think this can cause any damage to the motor or traction magnets so your milage may vary.
