Re: How to use parts, prototypes and materials in the garage????????

This is how you can install parts, prototype parts, and materials:

1. Go to your garage.

2. Select the car you want to customize.

3. Click on the type of upgrade you want to customize.

4. To install parts or prototype parts, click on the type of upgrade again to use the performance parts (or prototype parts).

5. To install materials, click on the material itself and then click install.
