I didn't see these at first. I'd still go used as Dolt suggested but if you insist on getting a new one, you're asking at the right time. Dealers are starting to want to clear out the leftover 2014/2015 bikes to make space for the 2016's. I'd check things out and see if any dealers have 14/15 883's on the floor and see if they are willing to haggle on a price.
Not sure where the fixed price thing is coming from, though. I think even with new, they are willing to work with you a bit but sportsters may be the exception. I was able to talk my dealer down from 13k to 9k and they cut the delivery and setup charges last year on my used 06 Fatty.
Delivery and setup on a 06 fatboy? I've never paid that on a used motorcycle.
