Well for one we have no idea if Toyota actually plans on selling the thing. Even if they do, it would be more of an image car than something they'd try and profit from. Honda originally did the same thing with the NSX when it came out. It was a "hey look what we can do" car that increased the overall value of both the Acura and Honda brands. Ford is doing the same thing with the GT. These companies are all so huge that you can really consider any one of these vehicles as part of their marketing budget.
