Well, apologies for the thread hijack and

by the way!, but since you asked...
...many years ago, our family had two Reliant estate cars (four-legged ones)! The were almost identical to look at - both white, and they were only one digit different in their registration numbers. My mum used one as a family car and my dad usd the other for work. He was a mobile mechanic and sued to cart all his tools and junk round in the back. Needless to say, it was absolutely filthy! I remember my mum berating him because she'd had to use it one day and had come back with a big oily diagonal stripe across her blouse from the filthy seat belt!
Anyway, one day, my mum was pootling along taking my little brother (who must have been about 3 or 4 at the time) somewhere, when all of a sudden she was stopped by a police patrol car. (That was in the days when they used to have those - now it's just yellow boxes on sticks)! The officer got out, put on his hat and walked over to her car, paused for a second, then leaned in at the window and said "I'm terribly sorry madam, it's not ths car we're after, but another one very like it". She was just about to set off again, when my brother piped up:
"is it a really skanky one with loads of junk in the back"?
"yes son, as a matter of fact, it is".
"that's my dad" (said my little brother, with obvious pride).
"well son, when you get home" (said the copper, desperately trying to keep a straight face!)
"...tell your dad to go and get some road tax"!
(and as a complete "aside", pretty much all my cars have had names)!
