I for one love Gyrozetter. It has all the elements you want in a giant robot series about cars. I personally love it. You can say it is depressingly awesome. (that is the main character's catch phrase). Also, one of the bad guy giant robots is like Shrapnel if he had a car alt mode. This series kicks so much butt. It even has a RIDER KICK!!! You also have your favorite cars like the Nissan Fairlady Z show up (Prowl, Bluestreak, Smokescreen) and Prius show up.
