You're clutching at straws now... The GT86, FR-S and BR-Z are the same car. Not just because they look the same, but because they were co-developed by Toyota and Subaru. Same chassis, same body, same engine, same brakes, same suspension etc. etc.
Yes you could argue that they are a different spec because one has alcantara seats and one has different stitching on the steering wheel, but if you want to go down that path we will end up with another Gran Turismo (which has no doubt been brought up in previous posts)
