The way I see it, here are the options.
1, buy a new truck, and add to the pollution it takes to make the thing, do this every 4 years so the planet has no respite from the factory's emmisions, even if the truck never turns a wheel it's already poluted the planet.
2, buy a tax exempt truck and fit a nice 80s cargo engine, tax exempt is exempt from the LEZ
3, register your truck in holland
4, buy a fleet of bicycle rickshaws or horse and carts
5,convert to petrol, I am sure there are a few 16L yank engines out there!! Would a 16L engine really use £200 of fuel a day more than a diesel?
Bear in mind this will apply to all diesel commercial vehicles over 2005 kg by 2010, so that's all transit sized vans, but not car derived ones. This is not going to go away, no matter who gets votedn in. It shouldn't have been let in in the first place. Do you knwo anybody who voted for this?
