Why are there never ferraris in need for speed?

The need for speed games have every type of car from volts wagon to pagani zonda but no ferraris in any of the series why is that??|||Because Need for Speed probably won't pay Ferrari enough money to gain access to the rights of their vehicles. Ferrari might also not want to be associated with street racing. It's a good question.|||I am 110% certain that Need for Speed Hot Pursuit II had Ferraris. They just don't get them anymore.
