Lupo 3L, one of my favourite eco cars, nice interior space from driver and rear passengers, nice looking(for this type of car), nice braking, handling with eco off is not bad.
I have recently done a turbo, intake manifold, egr and intercooler service on one lupo 3L, very nice engine, i recommend you to test the front arms, the turbo and check intercooler for leaking in the upper intercooler pipe.
But to be honnest, i dont think you can get 2L/100 unless your driving very slow at highway, its hard to tune a very well tuned car, to do that, you need to know a lot about aero and mechanic, but i dont believe in miracles.
