I'm going through the same thing right now. I'm not tired of the hobby but I got bored with my current hot rod, I'm already in waaaaay over my head on money and don't want to spend anymore on it. It's been "done " for two years now but I can't ever seem to stop spending on it.. I wanted to start something else, but no space or money and can't seem to sell what I have so,,, I put a cover on my Plymouth a couple weeks back and don't expect to uncover it much if any the rest of this year. One day it will either sell or I'll do another round of cash dump into it.
The newer R/T I've been trying to sell is getting traded in ... Giving up on trying to sell it outright too. I'm not giving up on the hobby, just taking a break for awhile to deal with some other life issues....
