If you were going to choose between these two cars?

I would say the '72.
The '70 has been fooled around with a lot and has a lot of visible issues, not to mention what it would be like in real life when you looked at the car in person.
The '72 car is a better car condition wise, but the interior is pretty shabby for being supposedly redone not that long ago.
To tell you the truth, i wouldn't buy either of them.
I would wait for a better car to come along, it's a buyer's market......
