There have been rumours around for a long time, most of it scare mongering. Any car that was registered in the uk after August 1st 1975, has to pass an emmisions test, and the number of cars registered before this are hardly likely to cause the melting of the ice caps.

There are however enough classic cars out there to bring London's rush hour, or any of the main motorway routes to a complete standstill at will. They wouldn't dare!

I hate to admit it, but it was the Tories who brought in the 25years or older free road licence,(don't get excited all you old codgers, that's the car, not the driver) and Gordon Brown who froze it to pre 1973 cars - yet another stealth tax.
