FWIW I'm planning on keeping my E90 for some time still. And screw F30Post. I like it here. Even if I owned one, I wouldn't play their lame game which is probably not even nearly as advanced as ours. So there.
So new challenge (thanks eriku for the approval):
Since we're on the subject of evolution, your E9x (or loaner F3x 
) with a dinosaur head. Doesn't need to be a freshly killed one, you can reuse a previously enjoyed one. (body can be attached)
