Getting them started young

I bought a 360 for my dart an all the things to rebuild it. Been waiting 4 months in the garage for my 9 year old to ask me about it. Ive been asking him to help me build it and he showed no interest in it. I bought him a model kit about two weeks ago and since then ive bout two more. We were building them last night and out of the blue he said "dad when are we gonna build that real motor for you car". We're gonna start saturday.
I figured if he wasnt interested in real car he would be interested in models. Maybe this is what will get him started.Heres hoping for a couple more mopar nuts.
