So the guy has owned the car since 1968, as much as everyone may not like it it's is his car.

Why should he have to sell it to appease others?

Apparently it's always been a race car, so what has changed?

The constant bickering about what cars are worth is one of the things that have taken the fun out of the hobby and made it more like a business.

The love of the cars used to be what motivated people to have them and actually drive and race them.

That being said, I would return it to the as raced in the 60's look.
But as stated, it's his car.
