There are hardly any OE Campy equipped bikes except really high end bikes. Usually ones with Record or Chorus. Most bike shop owners are not going to stock a $5-6000 bike on the floor unless there is a high demand for Campy or high end bikes.
Also, Campy does not offer huge OE discounts to manufacturers like Shimano does. They simply cannot do it. I read somewhere that if a high volume manufacturer (Giant) wanted to OE spec a road bike with Chorus/Centaur, they would probably decline. They would not be able to supply enough groups to meet demand. And also the fact they want to stay an exclusive elite brand.
Come to the shop I work at. Yes we don't stock Campy equipped bikes (because none of our lines offer it), but I personally, and a former employee/friend/teammate ride Record Equipped bikes. We'll let you take it out for a short spin to try it out. We then can work on a custom build.
