Given your location, $200-$400 is what it is likely worth. $750 is insane for that condition. Here is what Im seeing...
Janked up wiring
Broken switchs
Missing front fender
Bent rear rack
You can tell there are "replaced" bolts and some performance mods. Based on its condition the person that did that probably didnt know what they were doing so expect poor compression and just general jankyness through the bike. When i see mods on a moped i normally discover short cuts to the quality of repairs.
