well my theory is that if I can get good at it I can add it as one of my services as there is no one out here that does it. there's a few interior places but for some odd reason they won't build interior from scratch.. so I want to try it and see how it goes.. I think it'll be fun to. plus that way when I get done with a build I can say I built the car myself and didn't send as much to other shops, if ya know what I mean.. I don't do engine building either but a good friend of mine as built many for me, and he does it at my shop so it's still done there.. so the only really missing link would be interior.. Well and glass blasting but i'll probably pass on that one..lol
