Which should you choose?
We will not advise between these two machines, because the drive differs (4WD; Two-wheel or four-wheel drive); they were not built in overlapping years (2002–2007; 1992–1997). 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.
