I got it for 250€ and for that money it looks pretty good. I wanted a scooter that I can work on and for now it seems perfect. everything on the outside is all good.
I do not know much about scooters, but last owner said, that it gets some extra air from somewhere, but most likely it is not the motor, because he already checked it, also the motor has almost all new parts, except the cylinder, he said the cylinder should be ok. Also something is wrong with the air filter, the factory one does not seem to work, he said, that replacing it with a cone filter has helped him before.
