You can't (as far as I know)
If it looks rusty it's because you haven't bought a paint job for it yet.
It's "dirty" looking because you need to buy car body paint for it. Otherwise you cannot clean it.
you don't need to
Go on My Gaia and hit My Car. Sam will talk to you then.
Your fish tank doesn't need to be cleaned. It's always clean.
You can't,its not possible.
I think you are either a beginner on gaia online and you think there is supposed to be a license or you saw someone on gaia with the license, you don't buy one, but if you still think you do you can search the marketplace. But you don't need a drivers license to race in gaia.
Well you can't do that yet they haven't fixed that. ~Zizsuki AKA Shinked_Emo (gaia)
Click on someone elses car and select challenge, Then you will Race that person, But that's the only way you get to drive it.
If its that original cheap ugly car you first get, you cant sell it. You can sell the paint and parts that you baught though.
Scroll over the category "My Gaia" (next to "Home"). When the list of subcategories comes up underneath, click on "Car" and, if you haven't already picked out a car, it will take you to where you can choose from the cars for no gold.
idk if you can delete it but you can trade it in for a new one and to do that you just go the the car page and click the trade in thing then pick a car you want if you wanna add me its I_AM_CAM
