Hi! I always love to see people coming back to the Hobby as they get older. I did the same thing myself.
You're not the first guy that said he came from SA, I assume that stands for Scale Auto? I know there was a magazine called scale auto, did they go under or something? I just came back to the forum myself so I'm still kind of feeling my way around, doing my best not to offend anyone or ask too many stupid questions. I think I'm doing pretty good with the first part, but as for the stupid questions? 
Car models can be very, very cool, have you ever thought about making them move under their own power? Over the last seven years or so I've gotten heavily into radio control and I've been having a blast. I've even got a 1:6 scale radio control tank that shoots 50 caliber paintballs. I also really like to do military trucks so I'll be watching your work to see if I can learn any good techniques.
