I don't think E70-15 polygas GTs came on any factory musclecars as standard or optional equipment. (stand to be corrected) E-60-15 is a desirable size for 440+6, 440-4, 383 and 340 Cudas, but that's not these - I've seen E60s go for 2k in the same condition as yours. I wouldn't take less than $1100 though - car-specific or not.
