Have you checked NADA?
Sorry to say but you won't get any extra value for the work you've done.
Not for a 16 year old hybrid.
But since you're out West, where good used hybrids are rare, you might get NADA average retail for it.
NADA range is $3900 to $4680.
Don't add value for things that are standard or forced options.
Like a/c, furnace, stereo, awning and so on.
