Hi, my cupra had illegal plates on the when i bought it (not pressed alloy, just the wrong font) and i got pulled over buy the local traffic unit at which point they removed the plate from the front of the car and conviscated it and sent me on my way and told me to get some legal plates sorted asap, they also said that whilst traveling from the point they had stoped me at to the destination i was traveling to, if i got pulled over buy any traffic unit i would get 3 point on my licence and a £60 on the spot fine for failier to display a vehicle registration mark plate.
This was the first time i had been stoped so had not been given any previous warnings or anything like that.
