Hi,
The only thing I can help with is that I just bought an 05 plate GT JTD and its not marked with the M for modifica but it does fall into the lower tax catergory.
It is a great engine, I had a VW Golf Gt TDi before. Now when I put my foot down, its like regressing back to the days of star wars and the "Light Speed" scene, the diesel engine is truly fantastic eh?
