funny I did not see any GM products, mostly late 50's early 60's Plymouths & at the end a mid 60's Ford...
As to little car VS big truck....You should have seen the Malibu that plowed into the full size P/U that then hit my wife's SUV.... complete total of the Malibu, you had to look hard to find damage to the P/U bumper. I'm sure in a different situation things could have been worse for the truck.
