I've only been planet-side for a few hours, and already have found a suitable alt-form...I believe the humans call it a
Corvette ZR1...I found the specifications on a site linked from wikipedia, which is where I found the image of the vehicle. If I were as into my appearance as a certain Autobot, I'd be more vocal about my appearance...as I am not him, nor do I ever intend to emulate his personality, I feel no such need to describe my alt-form beyond the necessary adjectives and adverbs.
I did, however, overhear a few human males describing my alt form as "Bitching Sweet"...
...What does that mean?
Until next report, this is Showtime, signing off.
