We were smitten when we saw the Converj concept at the Detroit Auto Show, and we were not the only ones. Not many were expecting Cadillac to take the Chevrolet Volt's technology and give it this good of a re-skin.

General Motors must also be happy with the response because it's already talking about the compromises needed for the Converj to make it into production. Bob Lutz was hinting at a 2013 production date, and by that time the Converj would get a set of rear doors. But GM's management is looking to still keep as much of the coupe's body intact. The new doors would be masked as much as possible, including hidden handles, and the overally effect would be the “four-door coupe” look made popular by the Mercedes-Benz CLS.

A full-blown no compromises coupe is the kind of vehicle we prefer, but we also can't fault GM on this one. Two-door cars have a limited market appeal that trade a little less function for a little more image. So if the rear doors bother us that much, we'll just settle for a CTS coupe (in silver or midnight blue, please).
