I don't think there is any argument about LS6 convertible rarity or desirability...they are much, much rarer than a LS6 coupe... but the original comparison of value was between an LS6 hardtop VS a COPO Camaro, in which i still believe the 69 427 COPO Camaro (or 69 COPO Chevelle for that matter) is not only much rarer, but also more valuable than a comparibly documented RPO LS6 coupe. Personally, I wish the COPO WAS worth less, FAR less.... then maybe I could afford to buy one!
