should I buy

Here is an example of what people are asking. Needs all the body work. Absolutely mouse infestation damage. And probably needs engine work since the valve covers are and have been off.

1967 Barracuda Formula S | Classic Cars | Calgary | Kijiji
A much better deal than the one the OP is looking at, an all original 67.
You guys put too much value in a paint job. Most cars I see freshly painted in that condition are mostly a glossed over pile of ****.
This one fits that mold.
