As fun as it would be to build that up into a roadrunner or GTX, I've gotten a bit far into my cuda build to go trading it for a car in worse shape lol.
You could try getting a title for it. It's usually not that hard. Here in UT, I had to do that before. I just showed the DMV the bill of sale. Got an officer to run the VIN and say that it didn't come up stolen (he had to sign a paper), and the DMV got me a shiny new title for it.
