NORSK Data fleet manager Peter Carson favoured quarterly change. "It is bizarre that we conduct all the business in the car trade when everyone is on holiday. It needs to be shifted. I hope the new letters won't have any significance but no doubt the price guides will think of something. What I do hope is that we see a properly considered change rather than something half-hearted that will need tweaking every year.'

After a working life in the motor trade, Carson confided that he had never yet managed to have an August holiday.
