Not surprised you like it. I have the same 0.9 twinair engine (105ps version) in an Alfa MiTo.
You learn to drive it in such a way as to make the most of its: nothing, nothing, nothing, EVERYTHING... power delivery, by carrying speed and momentum through corners. With the sure-footedness of 4wd I'm sure your Panda is even more of a hoot.
Yep, perfect description of the engine, we have the 105bhp version in our current 500. It's like a car version of my old Yamaha RD350 YPVS. Huge fun.
