definitely possible to get it at invoice or below. my guess is that dealers expected the nismo to fly off the lots, so they ordered quite a few. most the dealerships i shopped at had plenty to go around, and if i waited a few more months i probably could've gotten a better deal - but alas i was impatient
anyway...just shop around, hopefully you're lucky like me and had around 5-10 different nismo's to chose from (within 75 miles)
