Kymco Agility 125

[Biker 1]

A friend has had a Kymco Agility 125 sat in a carpark for the best part of a year. I offered to get it going & sell it for her. Remarkably I got it started yesterday - the battery was still good(!!!)
Its a 15 plate with 18k miles, but is looking a little shabby due to weather... I can get a service kit including oil, filters, drive belt & plug for around £70 & will tart up the paintworks/rust over the Xmas break. I downloaded a service manual.

Questions:

Anything I should look out for?
Any ideas on how much these things are worth?

A nice round grand if it isn't too scuffed, gaffa taped or chavved up - quick search revealed this offering which might give some comparison;
