With over 1000 pieces to construct your choice of 3 vehicle combinations, this is serious Lego for older and more dedicated child constructors, who may (particularly at the younger end of the recommended age spectrum) need some support in producing their desired models. In view of the number of pieces involved, some form of sorting tray is to be recommended.
As usual for Lego, the construction pieces are well made and click together to form strong joints (just as well, considering the intricacy of the building task involved!) with highly useable end results. If looked after carefully, I can't see any reason why this toy shouldn't last for many years. The box could, perhaps, be clearer in showing that although it is possible to build 3 different vehicle models using the components supplied, it is only one of these that can be constructed at any one time.
The selection of vehicles is really popular with after school club kids - though be warned, if you're buying this set for more than one child to complete, you may find some disagreements as to whether the pickup truck with a trailer and quad bike, the dune buggy, or the flat bed truck loaded with a digger should be the first design project. I suspect that we're not going to see the dune buggy many times, as the best compromises seem to involve the pickup truck + quad bike or the flatbed truck + digger: hooray for the fact that these both generate 2 vehicles in one! The winch is also a big hit.
