Judging by your previous posts/threads, you will want to modify whatever you drive.
I love the minitrucks due to the style, individuality and fabrication/modification.
I recon a 00'ish Hilux xtracab, spend 10k on it.
Do some bodywork, shave it up, chuck on some decent wheels, and your set.
a canopy can be made to look good if you want it to hold more than one bike inside, or a stylish hardlid will safely contain the pride and joy.
Bonus is, its a full chassis job, and will fit a heap of engines, easily engineered, 1uzfe calling!
the standard engine is bombproof, and not that bad on fuel.
this is not mine, but could be easily achieved, and you can go anywhere from there.
