Depends on what the buyer has in mind.
Collectability?
Forget it, Car won't we stock and is on the WOVR so that will hurt value down the track.
Owner wants a Sweet modded car that probably has a more honest history than most modded cars?
Cars probably perfect.
A mate bought a GTP the was an Economic Write Off a year of so back. Was bought from Auction by a Panel shop and repaired very well and then used as the owners wifes daily. My mate then bought it because he wanted a gtp but didn't want to spend the $$$'s people seem to think they are worth.
Obviously you won't get the same return as a car with pristine history but I doubt you'd be into if for the same cost level anyway.
Personally I say rebuild it and keep it. You know you want to.
