That's an oxymoron, right? The comparison cannot be meaningless---the reality is F430 will indeed use up more fuel than Prius. If a benchmark demonstrates a true reality, how can that benchmark be possibly meaningless??? Same benchmark might be irrelevant to someone who wants to know how fast they can get from A to B, but irrelevant is not a synonym for meaningless! > You say that comparison is meaningless, yet you intend to compare those two > cars? I didn't say that at all, I was demonstrating fallacy of the argument that the comparisons were meaningless. > Any 'benchmark' has a goal.

Treating a benchmark as a binary win/lose is rather naive, it's not a competition, and (I hope) no serious person ever does that. A proper benchmark shows true strength and weaknesses so than a well-informed intelligent decision can be taken by an individual according to that individual's needs. The caveat, of course, is making your methodology clear and methods repeatable!
