I have three daughters 13,5,4 and the oldest one is building now and wants to do renders of real cars for the big three so she is on her way on what she wants to do by building models that started it for her. The other two I can see my youngest one not really wanting to do as to the middle one, Carolann already comes down to the room and looks at the stuff and plays with some of the toy cars I have so she is really getting big into it, as for the youngest all she wants to do is play with a horse name flicka.. So two out of three is not bad if they like it and keep it up and they are happy that is all I ever want them to be on what ever they want to do... Just be Happy and have Fun.
