I believe that the matter be children cling to mechanical or do not cling to and I think my son is not their thing. Both vehicles are really nice building, very big, funny but my son had it for his 3 years and now he was 7 and he never played with once mounted and he always asked him mounted when he wanted to turn the car on a motorcycle or vice / versa, it never interested to disassemble / assemble and I have a feeling that his brother who is 3 and a half years will not be more passionate but it ' is always good to know we will not purchase for mechanical biggest since it is not their thing. Otherwise if the child clings gear is really chouet, robust, easy to grip.
