Dont for one second think that they cant do this if they want to! My 1989 Merc 408 Recovery truck will be scrap in six months time along with thousands of others like it. I have the choice of trying to fit a Euro IV compliant engine, circa 6 to 8,000 pounds. Fitting a catylst exhaust system, circa 3 to 4,000 pounds or buying a newer compliant vehicle, 20.000 pounds and up!!! L E Z, I believed it would not happen and I signed an E petition to stop it! The kind folks at TFL ignored it and went ahead. They dont give a shit about the likes of us so get used to it!!
