Is there any car out there that the folks from California-based NCE won't whack the roof off? Probably not. If it has four wheels and a fixed roof and you can afford it, the California-based company won't have any problem at all to transform it into a convertible. After the Dodge Challenger, Toyota Prius, Cadillac CTS and God knows how many other vehicles, NCE has now chopped the top off a Mercedes-Benz CL-Class AMG coupe. No word if it's the $150k CL63 AMG or the $200k+ CL65 AMG, but either way, the owner of the car must have a lot of 'ping-pongs' (and way too much play money) to dare such a conversion.
