Restore them.
But don't over restore them (Polished shine) and you'll get a pretty penny for them.
They were likely clear anodized from the factory just like the door top trims were.
I know I'd definitely get more money for them restored, but I really don't have the time to do it. I also don't want to sink a ton of money into having them re-anodized.
They'll clean up some more pretty easily, I'll probably just do that. Plus I think the market for them is restoration anyway, and I'd hate to "do it wrong" and have them be worth less after I put time and money into them.
Does seem like they're pretty rare, but I also don't know how much of a market there is for them. Seems like most people clone their Gran Coupe's to something else and ditch the trim...
They are for sale though, I want to do some more research to find a fair price, but I'm open to offers if someone needs them.
