1/35 scratchbuild: maybe a lunar vehicle?

I used some bondo and styrene to fill in large gaps and widen an old Lockheed jet model. I don't know where the jet came from, but it wasn't built or painted very well, so I scrapped it as a donor. I'll likely leave the rear open with the engine exposed under a rollcage. Honestly the wheels were my inspiration to build a model like this.
