Seems like it, Z3 to Z4... and now Z5 as stated.
Looking at current trends, I'm surprised there is not talks of Z1, Z2, Z3, Z4...... :tiptoe:
What is most interesting is the Toyota link, and mentioned supra badge.
If the BRZ and 86 is anything to go by, well, then there should be nothing but good things to come, however, it better have a BMW 6 pod.
