Gordon Brown is expected to raise taxes substantially on larger-engined cars in Wednesday's Budget. Some reports suggest that road tax on the least fuel-efficient cars will double to about Â£400 a year. http://news.bbc.co.uk/1/hi/business/6464783.stm Not wishing to reopen the debate on this in terms of 'the environment' (some people do need 4x4!), but does anyone know what the fine is for not paying Road Tax if caught? Seems to me it may be a risk worth taking if less than Â£400? Especially if you have a clean licence. We all know that millions are never caught or fined, so stealth taxes like this are only going to encourage some law-abiding 4 x 4 owners to join them?
