Ha! My mother had a Vega before her Pinto! It was some green color and had a terrible rust problem ( to be fair it was ungaraged and we lived in coastal MA)
Those cars, like most of the cars built in the late 60’s to 70’s, would start rusting away on the showroom floor.
Recycled steel that wasn’t “cleaned” or “killed” to remove heavy metals was the cause.
Most people don’t realize that the engineered lifespan of those cars was four, maybe five years, and 80,000 miles max.
