In my not so humble opinion, a reliable engine with a strong transmission is 10X more safe then a car equipped with airbags that has a crappy engine that will strand her out in the middle of BFE.
I think statistics would probably disagree.
Being in a crash without airbags is probably more likely to result in injuries than being stranded for a few minutes while you wait for a tow truck. Unless you're in a horror movie, being "stranded" is more of an inconvenience than a safety issue. Also, a thoughtfully purchased and well-maintained car is very unlikely to leave her stranded anywhere. Hell, I had a freaking Chevette and I was still only stranded once! 
Those Novas were strong little reliable cars. And the fact that it's delivered contents unscathed through 3 accidents also says something.
Yes, they were, 20 years ago. But there are lots of strong reliable little cars available now that have more safety features. And don't have existing damage.
