Which should you choose?
We will not advise between these two machines, because their unladen weight differs by more than 25% (37%); the drive differs (Two-wheel or four-wheel drive; 4WD); they were not built in overlapping years (1976–1979; 1981–1984). The figures below are side by side so you can judge them yourself; each says whether it was measured, claimed or declared by its source.
