I've been building WAY too many customs lately. It creates a problem because, unless I have an order or commissioned car to build, I'm building what I like and they're hard to let go of. Sometimes I'll let loose of one if someone likes it more than I do. I'm just running out of wall and bench space to put them. It's not the money, understand... it's simply a space thing...lol
It wasn't too bad until I started putting them back on the cards. Wall cases and jewel cases don't take as much space, but some cars just need the comparison of what they looked like originally...especially more popular cars.
I even go as far as to save the small M2 cases from cars that I gut for wheels and parts. They don't stack as well, but they keep the dust off.
All in all, I gotta' either slow down or learn to sell some cars...
