Build a car online by visiting the website of a particular automobile manufacturer or by visiting a website such as Cars.com, Autobytel.com or AutoTrader.com and inputting the desired specifications for your car. If you have a particular car model in mind, visit the manufacturer's website to build the car, but if you are not sure of the brand or model you want, use a site that allows you to build cars from various manufacturers.
Nissan and Chevrolet are two brands that allow individuals to build cars online. On these sites, begin by selecting the vehicle model, and then follow the prompts as the site asks you to select options that include trim, colors of the interior and exterior, engine type, tires and accessories.
Cars.com, Autobytel and Auto Trader ask you to begin by specifying a make, model and year. Proceed through the prompts in which you select options similar to those available at the manufacturer websites. The advantage of using one of these websites is that you can explore the options and pricing available on vehicles across a number of brands without navigating to each manufacturer's website, and you have access to research, such as buying guides.
Regardless of the option you choose to build a car online, you often have the opportunity to see how much each option costs as you proceed through the screens. At the end of the session, you receive a suggested retail price for the car customized to your specifications.
