Well just had a we play with a Honda Civic Jordan. Least to say after a small b road blast and then onto the slip road to the motorway I fininally let him past when I sat on the speed limit. He past very slowly and gave me a quick nod off appoval. But I dont think he knows I it was a diesel that smoked him. I have to admit from second and third I gained 3 car lenths but he then stayed glued and went no futher back.I use good fuel and hardly any black reak is seen from the back. He probably thinks he's just kept up with a Cupra R.
