On average, SUVs consume over 6 miles per gallon more than a family station wagon.

Isn't *more* miles per gallon supposed to be a *good thing*.

$200,000 and they can't get a simple thing like that right.

It's awkwardly worded, admittedly, but it's not a mistake. You are apparently failing to note the effect of the word "consume" in the sentence.
