This long and low convertible was built for the 2014 SEMA Show, and now its about to a featured car in upcoming .Image Credit: RM SothebysWithout any modifications, the 1966 Cadillac DeVille convertible is a slick-looking classic with its slab-sided body, long proportions and lots of chrome, but this custom job took this car to the next level. After shaving off the door handles, some of the side body chrome and the front fender turn signals, this build was slammed with an AccuAir air ride suspension system and given 22-inch American Racing wheels. Looking at that killer stance, its no surprise that this car was exhibited at AccuAirs SEMA booth in 2014.In stark contrast to the black-on-black exterior colors, the semi-custom interior of this Cadillac is bright red broken up with a minimal amount of chrome. The front bench seat was replaced by low-back heated buckets split with a custom center console, while the front and rear seat upholstery has a unique pattern. While the Cadillacs monster 7.0-liter V8 remains unmodified with a 340-horsepower output, the engine compartment has been dressed up with a painted air cleaner and valve covers.Image Credit: RM SothebysThis custom Caddy will be up for grabs at , which runs from July 23-30.
