Decide on a budget for customizing your car - $20, $50, $100.
Step2
Take a look at your car.
Step3
Decide how you want to trick it out.
Step4
Consider the time period. If you want to keep the car in period shape, research body colors and wheel-spoke patterns from that era.
Step5
If it doesn't have a spoiler, consider adding one.
Step6
Add some decals. Decals may either suggest stock cars with advertising slogans or images, or historical periods. Use flames on the hood of '50s-era cars or airbrushed images on '70s-era cars, for example.
Step7
Continue adding things until your car looks as intimidating or as flashy as you'd like.
Tips & Warnings
There are no rules for how your car should look. Use it as a vehicle, so to speak, of self-expression.
Making the car too heavy may affect its performance.
