haha I've never understood the correlation between plates and years, sure it's very simple but never been arsed to work it out.
If Y = Letters, X = Numbers
The number plates are YYXX YYY
There are 2 numbers in the middle, X1 (the first X), tells you if its the first part of that year or second part. If it is 0 then its March to August. If its 5 then its September to the following February.
X2 (second numerical digit) is the year X5 is 2006, X8 is 2008
So 08 is a 2008 plate between March 2008 to August 2008.
56 plate is a car from September 2006 to February 2007.
