It took me a while to figure out what is Rat Rod.
According to Wikipedia:
The typical rat rod (an early 1920s through 1950s coupe or roadster): Early (pre-World War II) vehicles often have their fenders, hoods, running boards, and bumpers removed. The bodies are frequently channeled over the frame, and sectioned, or the roofs chopped for a lower profile. Chopped tops, shaved trim, grills, tail lights, and other miscellaneous body parts are swapped between makes and models. Most, if not all of the work and engineering is done by the owner of the vehicle.
Recently, the term “rat rod” (or rat car as modern cars are not actually hot rods like the name suggests) has been used to describe almost any vehicle that appears unfinished or is built simply to be driven.
