Hi Mike,
Our 'August 2007 4/4 version, when we had it, was Road Fund Licence £145.00
On this wiki site there is a chart (Scroll down) which shows that £145.00 is a 'Band G' [Band G (151–165g/km)] in 2008, the year that we bought it one year old.
http://en.wikipedia.org/wiki/Vehicle_Excise_DutyIt shows band G for this year Petrol/Diesel at £175.00
If you know your emissions then you should get the RFL rate from this chart?
I hope this that this is helpful.
Frank
