To use a self-build car kit, first select the model and desired specifications. Once the kit is delivered, use the provided step-by-step assembly guide and tool kit to complete each phase of the build. Each box contains a label that identifies the step where it is used. The build may take between 80 and 100 hours, and most companies offer technical support to address any issues that arise.
Once the car is built, it must pass a test that indicates it is road legal. Upon passing, the vehicle can be registered with the local Department of Motor Vehicles.
Custom self-build car kits are fully customizable. The body is painted the specified color and sent to a factory where other components are packaged. These include the fuel tank, brake lines, pedals, dashboard and wiring loom.
Requirements for registering a self-built car differ by state and country. For example, in the state of California, the driver must apply for a title and registration and have his vehicle verified by the California Highway Patrol to make sure the vehicle weighs less than 6,000 pounds. The driver must show proof of ownership, brake and light adjustment certificates for vehicles weighing more than 3,000 pounds, and a valid emission inspection. Additionally, the driver must pay all applicable fees.
