I've always been pleased with the "duststop" car covers from covercraft. Always fit very nicely without being super tight when pulling them over, and are usually good about options like spoilers and antennas. However when I ordered my cover for the XKR they did not have specific patterns for the coupe or convertible, just one for both, so I find that there is a bit of excess fabric along the hatch area, where I assume the convertible top would have had a bit more height?
