I'd cut it in half and do a custom chassis with C6 everything and a LS3 or 7 powerplant - but it's a sickness I have ....
It's difficult to make the decision to restore or modify one. IMO - if it's not a special version of the car (limited number, limited edition, special drivetrain or something - or a celeb car of some note) and they don't appear to be in high demand - or are in bad shape where restoring one is not feasible - you can mod it.
