Only thing that I would say in addition to what's already been said is that in my experience the VAG 1.8T engines are normally pretty good on fuel - if you're only getting 22mpg from yours, you're likely to get worse from a GTi-6 driving it in the same manner (assuming the 1.8T isn't distinctly broken of course!)
