Well, I'm confused, for sure... the information doesn't match what Parkers are showing...
http://www.parkers.co.uk/cars/road-tax/?deriv=21114
The above is the quote for my tourer, showing £210 for this year (08/09), which I have literally just paid (as of 15th March, to run from 01/Apr/08).
According to the sequence at the top of this thread, if I'm paying £210 now, then I'm in the Band F (186–225g/km) category... and thus in 2010/11 paying a maximum of £310 in Band K for the same emissions-levels (assuming a max of 225g/km taken from the top limit of that previous Band F range).
However, although Parkers also shows me in Band F now (£210) as expected... I'm in Band
L in 2010/11, not K, and coughing up £430!
They can't BOTH be right, and I've seen other, quite well-informed sites linking to Parkers... so I am now officially worried. And confused!
