Query: Most other cars won't go down the track....

This was a gift for my son's 3rd birthday...it was great for about a day. When he tried using any of his hundred matchbox cars, we found that most of them are too big to race down the track. So if you only use the two cars that came with it, it's great. Also, the race sounds are very annoying (loud) and it's touchy- if you just pick it up to move it, it makes noise- even if you don't tip the top up. This went to Goodwill less than a month after he got it.
