Are our Slants "Unsafe"?

My wife got rear-ended by a Chevy van loaded w/sliding while she was sitting at a light and they were doing about 30-35 mph by the driver's admission. Ahead of her was a refrigerated box truck (International cab/frame), which she promptly got slammed into. Front and rear bumpers, crumpled. Right rear corner very slightly bent, trunk lid slighty bent. Not a scratch on the wife- the guilty driver asked her "What kind of car is that?" My wife "A Buick." His response, "That is a strong car. " She drove it home, the damge was about $2700 all together to fix (I have friends and shop for the lowest price), and I love that car...'99 Regal GS- it just keeps on "Keepin' On!"
