A little background, 3rd vehicle for my son. First I picked 83 Accord. I kick my own a$$ for buying that one. 94 Intrepid ate water like a bitch. He blew it up. 3rd 89 Grand Am SE quad 4 auto. A good friend put a "rebuilt motor and trans" in it for his daughter and she didn't want it. It has sat since '03. I changed out tank, fuel pump and sending unit $200. We changed all fluid and filters it started right up. It sounded great. I drove a couple times checking brakes suspension etc and a-ok. Saturday morning I get a call and it died on interstate. I went and picked it up and the motor is locked up. Fluids look ok so I've seen posts of crappy oil system but I don't know. Is it worth rebuilding one of these? I'm leaning towards selling it to pull-a-part and start over again. The money I've spent already I could have bought a nonfixer upper.
