Sounds like it was a teenager's car.
You're better off without it - but you already know that.

I've picked up a few "freebies" over the years. Those first few turned out to be hardly free!
By the time I had the first few on the road, it ended up costing more than the cars were worth. Still kept them till they were no longer roadworthy and would then strip them to the carcass.
In time it was worth the efforts as the parts bins filled up. I could then get a freebie and get it roadworthy for next to nothing.
Granted, this was / is 140 series cars.

I guess what I'm saying is that I'd only pick up a fixer-upper if I had a healthy parts stash for the model.
