Pegasus Sky 50 – should I buy or not? !!!!Help!!!!

Hello scooter friends, I’m pretty new in things scooter, tomorrow a Pegasus Sky 50 will drive the 2nd model and if I like also buy, the engine should be new, the rest also looks good, the salesman told me that this does not go away under 600 euro at ebay and co. he wants 400 euro for it and also does not want to negotiate under it, it should run 2000 km but just new engine on it, he also told me that I should start driving slowly because the engine is new. Now I ponder in m a head whether I should buy it or not since I don’t like new engines, because these are just very sensitive at the beginning, just how long I don’t know. Can jemamd among you help me something, should I buy it. is a Pegasus sky 50 a good scooter that you would definitely prefer the department store or mobile phone contract scooter? please help. MfG.
