It's not uncommon for cars and bikes to go from dealer to dealer via auctions. A dealer watching their inventory could certainly dump stale stock at auction. It's also possible that it came from a dealer that folded. The Versys is not a high volume bike and certainly seems to sell better in some areas than others. I bought my '15 V1000 as a leftover in the fall of 2016 for around 10k. When I bought it there were several dealers around the state advertising leftover 2015 V1000s for the same price. I recently saw a thread on another forum where a dealer had two leftover 2016 V1000s for under 10k. Keep in mind if they bought it at auction, they likely got a good deal on it themselves.
It's probably a good deal but not the only good deal to be found with some research.
If I were you, I would push them to fix any cosmetic issues despite their "no warranty" statement. When you look at it, check carefully for damaged plastic that might be expensive to replace.
The urge to buy terrorizes
