..Then he went on to tell me that they didn't even actually break the Barracuda glass. They broke a back window from some Buick that was on the lot and used film editing to make it appear that they had broke the Barracuda glass...
They did a similar switch-a-roo in the recent 'Vanishing Point' remake. Instead of totaling a Challenger with 4 Ralleys, they wrecked a 67 Camaro with 2 steelies on the back...then in '99 they wreck a back half with cragars on the back.
