How much discount for 350Z???

Good evening! I got an offer for a new Nissan 350Z last week, because I’m just “back and forth” after the test drive. However, my dealer can offer me only 4% discount. I find that very little! Well, the 350Z is really cheap in relation to other “sports cars” but there must be still more in it or? That’s why I would be interested in what you got for discount. Thank you in advance With best regards Dominik
