If you want to free up some income for other things, then I would suggest going for the GTD. It will do it all, and is a great car clearly. If you fancy something different then the GTI would fill the roll. You know the GTD you dont mind the diesel type car, it's a good choice. The next/last thing to do it get in a GTIpp and see if you think it's worth paying for, take it out in the dry on you fav road with the diff in sport. if it doesn't feel like its worth it to you, the decision is made, GTD it is...
