Bike racer "Stavros" Parrish, late Barry Sheene`s best mate, had PEN15 on his car, but eventually the woke brigade saw an end to that.
Still kick myself for not buying a battered, rotten, non-running Honda 50 Stepthru in 1981. The numberplate was CUT1E.
Sold a few plates over the years, one being RUF 4X , from my Vauxhall Cavalier, to a dog breeder.
