I am stymied as well! From a market standpoint, ZL1s
should be considerably more than a '71 Hemi 'Cuda. It is a more rare car/engine package (69 vs. 108). They possess an infinitely more rare motor (in production cars) of 69 vs. over 11,000 hemis. Both possess incredibly terrific looks by most people's standards. '69 Camaro beat the '71 'Cuda to the punch on stuffing this enormous motor in a pony-size car by TWO years (in this comparison). Some things just defy logic.

Here is a decent market analysis (albeit mostly a discussion of 70 Hemi 'Cudas) from October 2005 - yeah I know, a LONG time in this market:
Hemi 'Cuda
One thing is for sure. This stuff makes for lively discussion.........
Do you think things might be a tad different if they had allowed a ZL1 option with a convertible Camaro?
