On Retention, has been valued at £1k buy a couple of the plate sale companies, I think they are wrong though.
£700
SOLD
Not surprised , seemed cheap to me
Sadly it went for less than the advertised price, I thought it was cheap as well.
Still amazed I have the roof, boot lid and doors as well. These seemed so sought after not so long ago they sold in days at more than I’m selling for 
Probably because its so quiet on here these days
I considered buying your plate Ade as I thought it would make a good investment
The guy who bought it in the end had it because his names starts with F.
I was always going to take it off the car as I wanted my Dads old plate on my car, that now resides on the Clio.
I had the plate on my car for 10 years and never had any problems with the police having it in correctly spaced, however I think that world is changing and badly spaced plates carry big risk these days.
Never had a problem with EX51GE M apart from MOTs , i was offered a fair bit more than that for it a few years ago at the MLOC Chatsworth do.
