^ I disagree. The supra didn't get a manual transmission because the Z4 didn't. You're overthinking it. But should you swap out the auto for a manual on your own? No, unless money is not a factor and you're down spending +100k on R&D to get everything working as if it came from factory. I agree about Toyota using the same engine for eons on other platforms, but this is the first time it has made a shared platform with BMW. I guess we'll find out eventually when news of the GRMN surfaces.
