Well, the majority of people having these old plates are usually
their very own treasure which they had when they bought their first
car.
Either that or that it was passed down by wealthy merchants in
the past to the next generation and it goes on.
A fact - the older the number plate, it will appreciate in value
and many such owners would not want to let these number plates be
transferred despite the high intangible valuation given.
The older the number plate, (numbers that are affixed to these
rare series) and which are on the road are typically bidded numbers
and it customary showcases and reflect's the owners's
accomplishments.
Take for example, I've got a a neighbour around 3-4 houses away
which have so called established a tradition - they own an entire
fleet of mercedes benzes marques which all carry the identical
numbers, with the S and E series. It's more towards a status symbol
and sense of identity among their entire family.
Number plates which are on sale in the market bearing these rare
affixes are usually not bidded numbers and are demanded by buyers
who just want an old number plate.
Well, as for my dad, we've had a few enquires before but of
course - it's not for sale! Most probably it's going to be passed
down to my sis. It also has had a fare share of being in the top
three prizes of 4D Draw. 3293:)
For my car number, probability that it will never come out is
extremely high - given the 3 factorials of "2" in it. (I've never
stepped into a 4D outlet and never will - coffer donations to me!
:P)
Hope it has helped you in gathering some information for your
project study!
