VW Lupo GTi

Hello!Bin new here..! I wanted to ask, as you have for experiences with the little GTi? I am about a year totally the fan of the Lupo GTi ! Would also like to know how expensive the consumption (at high tours (5-6000 U)) is? And how does it look with insurance? I still have something up to my Lupo, but I already know something.. Fortunately, well. And how does it look, can you also refuel super? Hopefully yes.. so MfG
