Building an AMT '69 Barracuda model, need some help

Seems to me its getting over complicated for a 5 yr old. You might consider some generic models for his "hands on" experience. Once he can read there are books on model building techniques. My very first model (Batmobile) at age 7 , turned out horrible. By the age of 12 cousins and I were competing. We used the oven burner to create body damage and primer spots, rolled rubber tires in brown paint then on tissue to leave dirt look in their treads.
I guess I'm saying dont take all the fun out of it from the start. Exacto knife detailing will come with experience.
