my 3 year old recently received this as a present. Obviously he is younger than the recommended age so Mum has to build it for him (never a problem as she loves lego!), but he is able to play with it on his own without problems. The build seems very durable for someone his age and we particularly like the clip on tow bar to join the trailer to the vehicle which stays togetehr much better than a hook and eye type. Other great features are all the accessories, the two fold down tailgates and the metal decals in the back of the vehicle. The other reviewer is right, the wheel base does look slightly odd, but only to me, not my son! Incredible value and a great set.
