The Mercedes-Benz SLC uses the chassis code C107. It was sold from 1971 until 1981 and was a coupe version of the R107 Mercedes-Benz SL convertible, hence the name SLC. Aside from the SL65 AMG Black Series, the C107 is the only Mercedes coupe based on a convertible and not a sedan. A variety of six and eight-cylinder engines were available. Though we don't know what rests under the hood of this car, eight-cylinders would be a good bet.
Based on the video, expect the SLC to follow more in line with Clarion Builds' BMW 2002 and 850Ci. That means a relatively stock appearance with an upgraded interior, a warmed-over engine and of course an upgraded stereo. Then again, the team at Clarion could go hog wild and make a modern version of the SLC rally car from the late '70s. Either way, we hope they ditch the terrible U.S.-spec crash bumpers in favor of the clean Euro look.
