I can tell you I know of a couple recent spec houses that sold for 20%+ off their original list just recently... at prices far below what the builder paid to build them.
As with most sellers these days, a good majority of builders aren't in as good of a position as they were a few years ago. They'll tell you the price, which is similar to an asking price any from a homeowner. This is only a starting point - what they would really like to get for the home. Is there room to negotiate? More than likely yes.
As Brad mentioned, it's hard to this specific home's value without knowing more information. If you're working with a Realtor (which you should be), they should be able to determine what comparable homes are selling for in that area.
If you aren't working with a Realtor - get one quickly. When working directly with a builder, they only have their best interest in mind and not yours. I've had friends over pay for little things a builder will throw at them, just because they didn't know any different. The one that stands out is a $250 charge for a programmable thermostat. These cost less than $100 at Home Depot (or Menards, Lowe's, etc).
