I have a  2005 GV250 in pristine condition 1250 mi [used for a local commute], that I want to sell.
I am turning 80, and the wife doesn't want me to ride anymore,
Any Idea what I should ask? could not find a 'Bluebook' for it.  It has rear box and the electric folding mirrors [very rare].
My local Kymco dealer [Portland OR],  doesn't take anything older than 5 years for resale, so I will need to sell it myself.
The dealer also told me that since Kymco stopped the GV250 in 2009, parts are very hard to find, so a buyer is on their own.
I also have the full service manual.

Neither the Rider's Manual, nor the shop manual for the Grand Vista 250 provided step by step instructions for the setting of the various parameters on the instrument panel.
There are three buttons - mode, adjust, and set.
The manual only refers to them for setting the time and date, but does not indicate how.
The other problem is that somehow, additional [unidentified] functions  are available with no instructions for changing, as well as how to avoid screwing up one parameter trying to either set another, or correcting a mistake
The additional functions are a trip odometer, a stopwatch, and the ability to switch between KMH and MPH.
Does anyone know of a detailed set of instructions for setting and using all these features?
I have sent a request for same to Kymco, but have received no reply. 
I keep screwing up my settings trying to make changes, the most frustrating is being stuck in the KMH mode
without knowing how to exit without screwing up other settings.
