I would guess these might be considered odd-ball and definitely rare.
I love the 60s NASCARs as they were really pretty much a showroom car with some nuts-arse engine in the bay may or may not have been in the actual car from the factory.
1966/1967 Chevelles are just too damn cool

That car to me symbolized all that used to be right with NASCAR and was pretty much at the end of the aero wars in NASCAR. It's funny becuz when I was 15 my uncle gave me 2 68 Galaxies and a 64 Galaxie (all rust buckets as I was never lucky, just born white trash hahahaha) and I HATED the fastback look of the 68. Now I wish I had the one with the 390 again just for the sake of burning tires off it.

1966/1967 had the coolest midsizes between the Nova SS/Fairlane 500 GTs.
Lastly, 1964. I don't know what it was about that year, but the Galaxie 500 and the Impala were at their peaks IMO.
edit - OK the car gods have spoken, a few hours after posting this I was watching TV and "dream car garage" had the car I was going to put as my #1 choice but didn't because not oddball - Bud Moore 70 Boss 302 T/A. It is hard to pick just one car, but I have wanted one of those forever. So figure it a sign to mention it. Holy crap, I am typing and "My Classic Car" is covering a 1964 Impala SS.
ooooohhhhweeeeeoooooooohhhhh. Time for bed before they start showing a classic NASCAR excerpt
