Which should you choose?
We will not advise between these two machines, because the drive differs (Two-wheel or four-wheel drive; 4WD); they were not built in overlapping years (1989–1992; 1993–2003). 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.
