Ok, I'll add another story to this.
Way back in the day, I knew this kid who had just picked up a base model Mazda 323. Nothing special, it's a light car, but doesn't have much go-go juice. A friend of mine regularly drove the family grocery getter - an Edsel. The thing was in nice shape, restored, running the 454 ci engine IIRC, and a bloddy big 4 barrel carb. This thing weighed a few tons, but had some serious power behind it too.
The kid with the Mazda was absolutely desperate to race this Edsel for pinks. And he was convinced that he'd win, too! I'd seen him race, and he could keep up with the Honda Civic of the day (this is in the mid 80s, of course) but there just was no chance he was going to hang with anything but economy cars.
Of course, if he'd had the AWD rally version of the 323, it would have been a different story, but that was definitely NOT the case.
