Can we take it that you have a personalised plate?
Two, but only one in use. The K155*** plate I originally bought on a whim on a DVLA auction and put on the Wife's car. Cost me £400. Within a week of putting it on the car another motorist pursued the Missus halfway across town to offer her £2500 for it. Not long after I had a work colleague then offer me £2000 for it for his Missus. I didn't buy it to make a profit, but when I'm done and finished using it I'm confident I'm make a handsome wedge, so ultimately it won't have cost me anything, won't be 'wasted' money.
For the present time I like the plate so it stays. This is good because I'm a lazy git and can never be arrissed to remember number plates, phone numbers etc, so I only need to remember one plate no matter how many cars I get through, just like swapping a SIM between handsets.
The other plate refers to my old regiment and was bought as a gift. The temptation is to sell it, but as it was a gift I can't quite bring myself to do so.
I must agree that a plate which only makes sense when spaced out illegally is a twottish thing indeed. Get caught twice, and the second time the DVLA have the power to withdraw the plate.
