IIHS provides a comprehensive test of frontal,side, and rear impact test and soon to be evaluated roof strength.[/quote]
Talking about roof strength reminds me of a rental minivan I rented in Oahu. I rented a Chevrolet Uplander (not sure about the model) few years ago there. When I picked it up at the airport I didn’t notice any damage. However during the week I noticed that the roof of the minivan was caved in. It looked like someone had loaded a heavy suitcase or something onto the roof and caused the external roof to cave in. I noticed it only because the root of the minivan was below my line of sight as I was coming into the parking lot.
The cave-in wasn’t noticeable from inside of the van.
The rental agency workers probably didn’t notice the damage either because your eye level has to be well above the roof to see it. I assume they usually look for damages around bumpers, sides etc, not the roof of a minivan.
I wonder which unfortunately soul got blamed for the damage.
