Most major car companies have programs online that allow people to "build" vehicles before they buy. Some of these companies include Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, Honda, Jeep and several more.
The car building programs that these companies offer do not allow a literal building of the car but a series of customization options, such as engine packages, exterior paint, trim, wheels, interior color, stereo, seats, trim and more. Once customized, the company gives an estimated price and options to buy or finance the vehicle. Designing a car and submitting for an estimate is not a commitment to buy the vehicle.
