Wow. I have seen some hand-made transforming cars, but this one was indeed made by professionals. It can also function as a real car and can be driven! Turkish Engineers Just Made A Real-Life Driveable BMW Transformer (Video) What's more, they seem to be serious about mass-producing these. You can check out the various planned models on their webpage. Letrons EDIT: heh, the various other models have the heads of existing Transformers. Bizmut has Prime Prime's head. Argon is Bayformers Prime Wolfram has WFC Megatron's head. And I think Tantal is DotM Leadfoot... maybe?
I was just about to post this. I wonder if they will get in trouble for stealing Transformers designs (TF: Prime Optimus, FOC Megatron and DOTM Leadfoot).
