My son got this car park for the 3rd birthday. The assembly instructions are indeed Needs improvement but the structure is not very difficult and can in any case plenty of room for variations. In the first fall trip tests the cars jumped on each ramp, resulting in accidents. At the top of the ramps fit a small nose is not belong there, since I have these removed at each ramp with my Dremel (see customer photo), creating even the heavy metal cars exit, often without Probleme.Ein great fun! The elevator had his quirks, he allowed himself to pull us not always because the slip clutch was too lax. So dismantled lift head, spring tension increases by stretching, now works also. Surprised me a little that at this price is not the way the designers to consider and improve so that the customer has to make fine adjustments such things.
My son likes to play with the Park Tower and otherwise he makes a pretty solid impression, therefore, still a 4 star (we had the tower at Amazon but only 69.90 + shipping cost)
