I've got nothing against personal plates - I had one on my A3 (plate up for sale soon I guess), so far my A4 has been more anonymous.
That's just daft money though. I think people willing to part with that much cash for a registration could probably do to reprioritise! That said though, if Mr/Mrs Singh has 14,657,524,842.23p in the bank, is a good and charitable person and gets the urge for retail therapy then best of luck to them! I guess you sell for what people will pay, so good luck to the seller too I guess!
Regards,
Rob
