How rare are FJ6 Demon 340's?

Thanks for the info! I am going to say it was a pretty rare color when new and it probably did not have a good survival rate. I mean if you were a kid in the late 70's and there were 2 or 3 Demon 340's on a used car lot and there was a GreenGo FJ6 car, I am guessing most would chose that car to modify and eventually destroy.

I don't think that's a good assumption. There are too many factors to make assumptions like that.

One also could say that a FJ6 car was out of the ordinary and might be more likely to be special ordered that built for dealer stock. And special ordered cars seem to survive and get treated better than cars off the lot.

Cars with lots of options have higher survival rates that stripper cars.
