A custom car is a passenger vehicle that has been either substantially altered to improve its performance, often by altering or replacing the engine and transmission; made into a personal "styling" statement, using paint work and aftermarket accessories to make the car look unlike any car as delivered from the factory; or some combination of both. A desire among some automotive enthusiasts in the United States is to push "styling and performance a step beyond the showroom floor - to truly craft an automobile of one's own." A custom car in British according to Collins English Dictionary is built to the buyer's own specifications.
