The art of customizing cars began early in their history, but it was the veterans of World War II who returned home in large numbers armed with the technical skills needed to modify cars that really got the community going. By the 1960s, major automakers caught on, with Ford offering the first car with factory installed optional extras — the Ford Mustang. In fact, finding a bone stock, base model first generation Mustang is almost impossible. Even those factory specials found their way into the hands of mechanics who made modifications to these cars, further personalizing them.

The practice of modifying cars as a culture and community may have started with American muscle cars, but it has spread nearly everywhere. Boy racers the world over spend hours under the hoods of their Honda Civics, souping up engines and lowering suspensions. High-end mechanics like Brabus and Alpina modify high-end executive sedans so they can outrun Ferraris on the Autobahn. No matter what kind of car you have, there are aftermarket parts that, even if they don't make it go faster, corner better, or stop faster, will make your car more "you." Picking the right parts can be tough! Take this quiz, and we'll tell you which aftermarket parts you should install on your ride!
