Woodsy, your plastic space tank ATV is a mosh of sources

and up close ....
The front half is a copy of the cockpit portion of the Macross SD Valkyrie toy.
The cockpit bubble is missing, probably to make a seat area (based on empty slot behind the large opening in your picture which probably was an attachment point for a windshield bubble that opened and closed) and not try to duplicate the rotating cockpit of the original.
Here is the Maximilian Jenius version in flight mode

but the cockpit is rotated to the shield side for when it is actually in battroid mode.
The Max and Fokker versions in battroid form are also similar with the cockpits in flight mode revealing the interior.
I've got my SD (super deformed) VF-1S off in storage so here's a bunch of pics off the web, hope these work.

I'm not sure if Matchbox ever released the SD toys. They were responsible for a lot of original toys for the Robotech series although the ones they used the original molds for (SDF-1, Monster) they cut corners on.
The SDF-1 lacks all the launcher mechanisms and the Monster is all in 1 color.
