Are our Slants "Unsafe"?

I work full time for a fire dept and worked for years in an autobody shop (now part time). While there's nothing cooler than cruising in an old classic, (like my 69 dart, or my 69 valiant), I would rather my family drive something new. Old cars ARE built stronger, but lack the engineering that make new cars safer. I've responded to hundreds of calls and seen safety equipment work the way it's intended (air bags, impact beams, crumple zones...). Sure our classics may appear to fair "better" in an accident, but I'd rather see my family walk away from a crash and let my insurance company pay for the write off than chance death or serious injury.
