There is also no incentive to do anything on older cars to make them more ecological, at least in germany you can get the lower rate of road tax by fitting a cat, ok it still costs more than the uk, but at least you've got the option as opposed to having to pay that rediculous top rate amount that you've quoted before.
I just wish there were more motor manufacturers working on updating their old cars to have lower emissions & better fuel consumption, rather than creating all these modern cars which infact are worse for the environment due to their complexity & reliance on rare elements.
The green thing is just a smokescreen for a lot of companies & govts to raise money off gullible punters.....
