A2A Quattro Licence Plate?

So does anyone know if there's any Ashes to Ashes discussion out there about the possible significance of the Quattro's licence plate?

It's: JLY 7 5IV
Which I'm guessing could be July, maybe July 7th 1954??  The only other thing I've got is from my media student friend whose recently been trawling through 7/7 newspaper articles, and she was like its July 7th 05.  This makes little sense to me though and i would shun my show if it were true...

Any other thoughts?

I'm just overanalysing here because I spotted something little in 2x08 which meant something and got all excited about my special clue spotting skills :)
