I will try to find a picture of the mecha in vehicle mode before transform. I don't recommend watching it it to anyone new to anime as it turned out to be fairly explicit and rather shocking. I'm a mecha junkie so it was fine for me, but it was was way over the top and not suitable for polite company.

Here is a picture that's not too bad even though it could stand to be closer up: http://i.imgur.com/bKMzinP.png
