CCM 404 for me, had 7000 miles of road use on it, 3 years old, and from a dealer cost me £2250. Cost less than £200 for knobblies, bash plate and handguards, so far I'm up to 14,000 miles, and replaced only consumables, at sensible service intervals, including 2 valve shims.
I reckon it's now stopped depreciating, and I could still get £1500 for it.
It's definately not for sale though.
And thank you for stopping the advertising in the forums. It was winding me up something chronic. If I want to buy, I'll look in the For Sale section!
