Which one should I take? Piaggo Fly 50, NRG DD or SYM mio?

Hello together now 16 and can finally take the scooter test and then get to me. But unfortunately I am quite unwise, which one it should become. Have you had experience with one of these three? Which would you recommend me? Are you actually more interested in more sporty models (NRG), but I don’t know if I should spend ‘so much’ money on a scooter if I could drive anyway in two years. And that’s why the fly is also in the game. men ; ) And yesterday a friend recommended me the Mio of Sym, but I don’t know it at all. Or can you recommend a completely different one? Of course a Vespa would be my dream (LX 50), but you have to pay quite well, right? Wouldn’t it be nice to have your reviews and recommendations : ) LG
