How much are classic plates and is it cheaper than regular plates?

Not sure but i believe it depends on your Taste and needs..

Same price I believe

Same price. But classic they base on the amount of miles you are giving a year to drive that car. So if you go over the miles. Example 10k a year. If you go over you will pay. Let's say 16 cents every mile you went over. So be careful. It can be pretty expensive. If that's the only car you have. Classic plates are intended for classic. Cars.
