If there's one thing we can be sure about SEMA, is the abundance of custom proposals for Detroit's trio of muscle cars - yes, we mean the Mustang, Camaro and Challenger. You can find just about any type of tune including some that don't make much sense like this here example of the new Dodge Challenger from Radiatnz Inc., which blends old-skool parts such as the vinyl roof top and chrome trim and bumpers with modern day amenities like LED lamps.
