Several years ago I towed a 1965 Impalla SS convertable 26 miles up and down hills to get the car home. 2.3, 4 gear. No Ill effects on the car. .
... thats one tow story.
And another...
Also don't let your sister drive the Pinto wagon when towing a 64 chev impalla with a chain. She drove away without making the chain taught first.
Ripped the bumper right off the pinto and damaged the quarter panel as it came off. The guys at the garage where we were
couldn't stop laughing as I quickly re hooked up and drove away properly. ( I drove this time, she steered the 64)
