The wheels should be black, as the car has full wheel covers. Was this a white car to start with??? No underhood or in-truck pics at all, no engine shots...this would require a PPI, as a minimum! He is VERY optimistic at that money for what we can see. I agree with the $6,500 figure.
BTW, those appear to be original Chrysler wheel covers for a '66 Newport...not 100% sure, though. Definitely NOT for a 300!
