Not everyone has loads of money for high caliber restorations. Most (I'd say 95%) of the cars you see at the local shows and cruises are of nice driver quality. Lets face it, the high end 6 figure restorations aren't driven and almost never come out unless the owner wants to knock it down to #2 condition. Actually the driver quality cars have become more and more frequent as more people want to drive and enjoy rather than sit and stare at the car.
Another fad that has really taken off in the last 5-8 years are original unrestored cars. I own a couple of those here myself. After 45+ years they can't compete in restored class competition, but they still present very nicely. That doesn't mean the car should be or needs to be restored. I guess to some they are cars that haven't had "attention to detail"
But it's actually quite the opposite. Lately they have become even more desirable than high end restored cars in some cases.
It's all about what the owner wants out of his/her car, and I'm not going to bad mouth either way. As long as they enjoy it, that's what it's all about.
