Query: Cars = great! Track = Meh

Well, our almost 5 year-old son loved the cars but the track was very disappointing. Like others have stated, VERY difficult to put together and even harder to STAY together. Then, after (constantly) ensuring all track is nice and tight/level, the "action" lasts...5 seconds. ??? The longest the cars stayed "active" was two laps and then they quit, with or without a crash. Honestly, we couldn't get the cars to crash more than 1 of every 10 times.Soooo, son made the best of things and just played/crashed/smashed them together. He thinks that's cool (whew!). Dad here sure is grateful that the cars are robust and when crashed together are pretty cool.CARS = 5 StarsTRACK= 0 Stars
