They have front plates here as well for 15+ years, although I never run them and only had one mention of it.
When I had my 99 WS6 I had put the plate on, but then found the front plate cover and put that on so it wasn't visible anyway. I got pulled over once when I was doing >5mph over once in that car and the cop was a dick right out the gate. When he mentioned I didn't have a front plate on the car I told him sure I did. He went and looked again and I told him it was under the cover he was looking at lol. Yeah I was young and dumb, but he didn't give me any infraction for it. He also happened to pull me over in front of a strip club and after he gave me a written warning for my speed a couple mph over the limit, I asked if he wanted to go in for a drink to relax a bit, but funny enough that question alone didn't seem to relax him.
These days they really don't care and are even talkin about getting rid of the front plates to save some money.
