Aye Cap .. ragtops are nice to look at .. I have owned one (a '63 Ford Galaxy vert with the 390) .. doubt if I will ever own another.
Reason is the temperature outside has to be in a pretty narrow range for it to be a top down day.
If it's way cold out, ragtops are just not well insulated.
If it's way hot out, see above.
One of the features I really like about the coupe Vette's is that panel across the top comes off for the 'top down' days,
..and it's fairly well insulated to handle all the other days.
(the small volume that needs heating/cooling helps also)
I am spoiled rotten just settin the temp at 70 degrees
and the heating/AC in the car just keeps it pegged there no matter what's goin on outside.
