Which should you choose?

We will not advise between these two machines, because the drive differs (2WD; Two-wheel or four-wheel drive); they were not built in overlapping years (1958–1962; 1948–1955). 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.
