Came across this in Zellers today and I couldn't pass it up.
It actually works better scale-wise than I thought it would looking at it in store. Don't have a roddy or mirage, but they'd fit if they're not wider than cliffjumper.
It'd take a bit of work to Mod it up, but the end results could be pretty good. Will need to remove a pin to get the cab off and also deal with fitting the feet under the front end.
Picked it up for $15. Its called gas caps, by Maisto. Cab lights up and plays music too, with the push of a button. The license plate and stripes has me wondering if it was a deliberate transformers homage.
