I'm in the process of restoring one of these buggies actually.
Fun fact: LaTrax Hustlers were all originally white (I have the original box for mine). But for some reason, the flexible white polycarbonate-ish (but probably not polycarbonate) body shells have turned light brown with age. Mine looks just like the one pictured above. It gives them a rustic, aged charm...like desert dust.
Also, this model evolved a little while in production. I actually have two, and one came with an earlier fully-metal radio with a steering wheel on the front (like an old school Futaba), while the other has a more conventional 1980s plastic radio. The car itself also changed a little. The included 2-piece saddle battery was always fixed in place by plastic ties, but it's a different battery across my two models. Also the heatsinks seem to have changed too.
My buggies are basket cases, so I'm just restoring one out of the two at this point.
cheers,
H.
