Talking about something built in say last 10 years. Round tube cars. At what point do the builders say, it's junk.
HTF took pretty big shot at Eldora. I'll bet needs rear clip and part of front. Needs all rear suspension attachment tabs replaced. The tabs where the bolt-in, supposed to save the chassis brackets, bolt too. RF has a-arm uprights damaged & I'll bet the rack mount is moved.
At what point do you just let it go? Turn it into a crate car or modified.
