Which should you choose?

We will not advise between these two machines, because their unladen weight differs by more than 25% (26%); they were not built in overlapping years (1984–1986; 1997–1999). 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.
