So is it a guess? Sure… and guesses can be wrong (that’s why Consumer Reports has removed their automatic recommendation for Toyota). But it is no more of a guess than it is with any Honda or Toyota model…
What I use is PAST history…GM’s history in build a reliable vehicle for the past 30 years is MISERABLE. Where as Honda, Toyota and Nissan haven’t been. They’ve proven to be far more reliable then GM. There’s guesses and then there’s EDUCATED GUESSES.
