Seriously, I will.
This does not mean you cannot work on your car. It just means if you are driving a 1995 (or by your age, 2020?) Toyota Corolla, you cannot tint the windows,add rims, put a spoiler on it, or do anything else like that to it.
Why?
Because you are wasting your money while driving around something that makes everyone else including your parents question your sanity.
