I find the Supra to be the nicest of the Roadbots. It has a few issues, but with a few slices of a hobby knife, I managed to allow his shoulders to rise, which improves the toy dramatically.
I also like to fold back the shoulder kibble behind his shoulders and opening the car doors wide as "doorwing"-ish kibble.
With these mods I'm able to pose the toy a lot better, and he looks a lot cooler holding his weapons.
Also, you can peg his "bumper-blaster" in his fist so he has a nice, tasteful pistol.
In spite of his lack of blue, his altmode and head design have convinced me to use him as a toy representation of my fancharacter Detour.

The Humvee is a nightmare, though. It was my first RoadBot, and if it wasn't for Supra-boy and your reviews, I probably would've called it quits then and there.
