Hello, I’m looking for a good used scooter. Unfortunately, don’t know me at all about it. Have one in mind, Rex 450 Good condition with 7000km, BJ 07/2006 for 300 to 400 euros. My question is the scooter worth the money, and what do I have to pay attention to when buying?!? In the description there was a cover mark, but what does that mean?!? What is the cost to me?!? LG
