There's at least one bit of it left in Antarctica:
Tthe commentry says that it was "returned home", but that may just be an assumption? My guess is that it more likely to have been removed as there is a lot of stuff left around the huts and there is no trace of it.
The later "traditional" way of disposing of rubbish was to take it out to sea and leave it on an ice-floe to disappear when the ice broke out. This fate may have befallen this car, but I suspect it is unlikely.
Interesting to hear if it is at least semi-intact anywhere.
