Well mine will do 60mpg on a run similar 0-60 with revo. Lets not get into that gti vs gtd as they are both great cars and we are lucky to own them.
To be honest there is no GTI vs GTD. That only comes from GTD owners who wish they owned or had bought the better car. Unless your actually telling us the GTD is not only more desirable than a GTI
but its also the better car ? Please say you are, please.
Kev , I think you know that I had a GTI on order , but got P**** of waiting for it to be made and lost the will to live!! Previous to that I had 5 GTI's all mk5's including ed30. I will always defend the GTD mate becuse its an excllent package with DSG!! If I was to go for the mk7 then it would be the GTD twin turbo??? 
Mate, you can defend your GTD for your life. Its a great car, its also the car you own and I wouldnt expect anything less. I naturally do the same. But we have to come back down to earth at some point, and there comes a time when one has to grasp reality a little and recognise that although the GTD is a fine car, its not more desirable, its not faster and its not a better car than the GTI.
