I've got a "cherished" number plate on the family car - not on the vans.
Got it by chance - won't post it here cuz I'm paranoid but it's A2 *** and nothing to do with my or my wife's initials.
Basically in about 1999 or 2000 ago I bought a 1992 Rover 420GSI saloon with a personalised numberplate from a widow who was selling her husbands car after he died. He was in the IAM and it was well looked after with leather upholstery and for it's time it was a quick little car with a petrol 2.0 injection engine.
I kept the number plate and transferred it to my next car (Rover 220 diesel and the next another Rover 220 diesel and then put it on retention while I had a Rover 620, a Volvo 340, a Volvo 240 estate and a Honda Accord Aerodeck 2.2i estate) I then transferred it to my Pug 406 estate and now the Suzuki SX4 2.0 DDI.
See, how interesting was that?
