If someone mentions owning a "hybrid" vehicle, most people assume it's a Prius or some other ordinary commuter car powered by a combination of gasoline and electricity. However, the term actually represents anything made by combining two different elements. So in a broader sense, a hybrid build can also be a vehicle that blends visual elements rather than powertrain components. Case in point: this 1973 Nova SS might not look like a '73 at first glance, since it features a front-end conversion with parts from the previous model year.
