WOW! I thought we had a hard time finding K-cars. Try finding a 1973-1977 Pontiac LeMans 4dr. I looked online and only found ONE! But, oddly enough in California, I have seen several of the colonnade 4dr bodies in the last year. Notably:
I saw 4-5 70s Buick Century/Regal 4dr Colonnade Cars driving aroud.
2 Oldsmobile versions.
Isn't funny how Buick is the survivor. I think I saw ONE Chevy version.
