for all of his cars. There are websites to do this. You just enter your real plate numbers and put your registration stickers on the plates. Problem is, they don't use reflective paint, so they're illegal.
My friend got pulled over 4 times.
He finally registered a 'business' in Montana and then registered all of his cars (4 total, I think) so that he could order black Montana plates. TBF - Montana has like 50 options and the black options are actually pretty cool.
He obviously didn't know about this new hack from OP.
Seems like a lot of trouble to get black plates.
