The website provided by NADA does provide scooter prices online for free. You can find these used values under their motorcycle section.
For example with your Honda Elite scooter, from the above webpage you would first want to select the manufacturer (e.g. Honda).
Then specify the year your scooter was manufactured and select the link for the Elite model you want a value for.
You will then be provided used values for the base model along with options that are available.
