I want you support to lobby the government to bring in a flat rate of motor tax on cars older than 10 years So, for older cars, there’s one rate for engines smaller than and including 1549cc and one for engine sizes larger than 1549cc. This is inline with the UK system http://www.direct.gov.uk/en/Motoring/OwningAVehicle/HowToTaxYourVehicle/DG_10012524
