Ditto to what everyone has already said. Understand that the GV 250 is an excellent scoot, but it has been out of production for years. Some replacement parts may be difficult to locate. Assuming everything works, including the power mirrors, and the scoot has a clear title with good, consistent service records, the price is reasonable. BUT that is for a scoot that works well, rides well, and has been checked out to ensure no hidden problems. Do your due diligence.
I have a 2007 GV 250, and am really pleased with it. I bought my bike used from the dealer who originally sold it to its first owner, and maintained the scoot for all the years before I bought it.
