The Decepticon cars were all awesome, but I didn't think Soundwave's vehicle mode looked enough villainous. It was okay in the movie, since he was pretending to be just a normal car, but the SLS AMG feels more like a Bond car or something, especially in silver. I wish they had found a way to work the Stunticons in, though. They wouldn't have to be G1-ish, or combine, or anything. I'd just want a team of Decepticon cars. One of the main vehicles I would have wanted as a Decepticon is a Dodge Charger. That would have been awesome.
