Hey guys so I’m gonna buy a modified car but I wanna know when you get pulled over by the cops which will probably happen, how do you know if its illegal or not because the mods are already installed when it was bought.

I’ve heard about having engineering certificates of each modification but don’t know much so appreciate the help. Can you just get an engineer to approve your car with paperwork and that’s all you need? Can the cop say that it’s illegal even when it’s approved?

How do u not get defected with a modified car, what paperwork do u need to have?

The seller gives a fat list of the mods but checking each one would be pretty annoying cause there's literally like 4 pages of mods done. Can you try to get the car approved by an engineer instead of checking each one and they'll check whats illegal and then you can take it to a mechanic to fix it?

Appreciate the help
