from what i understand about the car business, you can pay a fee to a private ins ution that can give you the average dealer cost on any make/model you want.
from here, you fax/email every dealership in the state until you find someone that is willing to give you the price you want (which may not be the exact dealer cost, but you now have an idea of the gross profit being included in the deal)
someone will sell a car at their cost just to move inventory, and probably to have upgrade potential down the line.
oh and DON'T LEASE! (unless it's a copier

)
