I am currently in a slump also. Finally I realized why I abandoned my last build. I just didn't want to deal with another full-body car. Oh, I love modern cars for sure, but all that chrome to BMF, elaborate dashboard detail, etc. Meh.
Then I started to think about what I think about when I am not at my bench. It's a build that has been lurking in the back of my noggin' for a while now. The more I thought about it, I realized that was the one I HAD to build.
Now I am in the planning stages. Once I think about what engine, wheels, tires, paint, etc, then I plan on posting some mock-up photos.
I hope I can work this way out of my block.
