Which should you choose?

We will not advise between these two machines, because their unladen weight differs by more than 25% (35%); the drive differs (4WD; Two-wheel or four-wheel drive); they were not built in overlapping years (1982–1993; 1975–1980). 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.
