Urbestfriend says it depends if it just fell over in the garage or
it got run into by a deer on a state highway. Panel damage
scratches, etc. are usually apparent. What isn't is the plastic bosses
where it screws together. There's not much strength in each panel,
but when they're bolted together, then they stiffen up. I have the
most trouble with the rocker panels on either side. They are long
and have extended plastic tabs to hold them on the rear. I also
had something fly up and rip the lower panel behind the front wheel (GV).
If it starts, doesn't leak oil or gas, goes straight and the handle bars aren't
bent to either side and your brake levers aren't bent. You're usually in decent shape.
I recommend using JB Weld. Sooner or later, you'll find cracked plastic
tabs just from normal vibration. Most of the joy in having scooters
is doing the work yourself. Most manuals can be downloaded anymore.
