While Cadillac busies itself with a 2-door version of the new CTS sedan, the folks over at Coach Builders, Ltd have been busy taking their tops off. The boulevardier CTS gets an insulated, hydraulically-powered roof fitted with a heated glass rear window and cloth headliner. The top also comes in several colors. Judging by this pic, it also looks like a fair bit of work has gone into making the car look good with the top down. No word on what happens to trunk space, however.
