Perfect number plate

I did a number of jobs today including checking our Morris 8. It started first time so I let it idle for a short time to keep the battery happy. It is stored across town so I then went to Auto Restorations,  which is nearby, to arrange a Warrant of Fitness appointment. This is all very important as our neighbour's have asked if I could drive it for their their wedding car on February 22nd. This will be the 7th occasion that the Morris has been used in this role.
I spied a Rolls Royce at Auto Restorations with the perfect number plate. I imagine that the plate is worth a lot of money.
