bummerpost is just mad because:
1. They're badge whores
2. A BMW is sharing bones with a TOYota
3. They aren't getting a Z4 coupe. Well at least not one with their preferred stylings :p
4. Supra is undercutting their Z big time
5. They're badge whores
They could, but that was never the goal of the Supra. Toyota wants a some what afford car so more people can have the chance to obtain one. Look at the LC for example. It's too damn expensive and has not even came close to it's sales goal...
A break down by model. GT-R and Cayman cost the most to keep up with.
