Tbh,outside of the vag group your options are pretty limited, top of my head things to look at; 1) Renaultsport Clio 200 2) Abarth Punto 3) Colt Ralliart 4) Corsa Vxr 5) Golf GTI Ed 30. Small engine doesn't necessarily mean cheap running costs. I'm getting an average of 34mpg out of my Clio 182, reads 36 on the dash!
