Hmmm. I don't necessarily think that's a great deal. To be fair I've owned my Bullet for a good 10 months so its been a while since I played the haggle game but lets look at what we do know. It's a 2011 which means its already fully depreciated with the 2012 being sold.
I would play the RV Wholesale places game, that are in Ohio and so fourth and work your best deal to see if the price you are quoted is in your neighborhood. For me they were 3K cheaper than my local dealer. My local dealer WAS NOT HAPPY and tried to talk me out of it but in the end matched their deal within $200 bucks which in turn saved me a 10 hour trip!
Good luck.
