According to the DVLA website (
http://www.direct.gov.uk/en/Motoring/OwningAVehicle/HowToTaxYourVehicle/DG_10012524), the following charges apply:
Any car registered before 1/3/2001, with an engine size of over 1549cc, 12 months RFL is £185
Any car registered after 1/3/2001, gets 'banded' according to the manufacturers stated CO2 emission level:
Band E (166 - 185 g/km) £170
Band F (over 185g/km) £210 (my '52 plate Disco is in this band)
Band G (over 225g.km and reg after 23/3/06) £400 :shock:, this is the so-called 4x4 tax
However, if your vehicle (regardless of age I believe) is registered as LGV - Light Good Vehicle (my '53 plate 110 Td5 is), then you pay £180 for 12 months pleasure of driving on the roads !
There's a small bit in May's LRO (page 173) in which Neil Watterson says that the recent budget changes mean that a 2001 Td5 Disco gets a RFL increase of £250...........but there's no mention of this on the DVLA site :?
