Triple the number of pieces as in the original 3-in-1 set, so you can have all 3 models built at the same time! In great used condition. Comes with three different sets of tires so that they each look more appropriate for the type of vehicle (the modern road tires and rims didn't look right on the other 2 vehicles). Building instructions are available on Lego's website. Comes to you fully assembled and packaged with care, though some pieces may come apart during shipping.
