My two boys 3 and 5 years, who have had green and red for Christmas love, even if 5 years turns out to be a little too large for comfortable use. Especially the trailer and the raising the hood to play repair. The pin of the green trailer broke on first use, a little disappointed on this point, but for now the rest holds up. However I tried to mount one and frankly I really drooled, and I finally had to ask for help. Yet I defend myself pretty DIY, but the rod of the steering wheel must be pushed at the same time you press the wheel and that the screw slides otherwise the holes are not aligned, except to have 3 arms I do not see how. To get straight to insert the wheel locks of the trailer as it was looooooong .... and to remove the hood pins and fix them in the slots provided, here too we still have a lot of strength.
