RE: New 2015 XP 1000

I recently bought a new 2015 RZR XP4 1000 sight unseen on the basis that it was a brand new model in California. Apparently they received these from the mid west however the one they showed me had 15 miles on the odometer, worn tires, minor damage to the plastics and no owners manual or tool set. I’m getting a decent deal at 22k OTD (for Cali) with a 5 year warranty but should I be worried that this was a demo model or something else? They did replace the tires and rims with brand new ones and I checked the air filter and it appeared to be new but still suspicious. Thank you for any advice.
