Somebody's spotted this trio of sports cars hiding under wraps near Minaret Summit in Yosemite National Park. What do you think they are and what are they doing in the Sierra Nevadas?

Apparently the vehicles were sitting unattended when this picture was taken a few hours ago. There's obviously a big old wing on one of them; and based on how beautiful the mountain pass is up there I'd say the cars are getting ready to throw down in a video shoot.

Thoughts and theories?
