Assume you mean “libel”, not “slander”.Suzuki Samurai, Isuzu Trooper, Lexus GX are the worst examples of their “journalism.”
Parties accuse other parties of things all the time. Does not necessarily mean much.
But what’s interesting is you not mentioning what the results of the Suzuki and Isuzu lawsuits were.
I’m not aware there was ever a lawsuit following CR rating the GX 460 as “don’t buy”.
No doubt Suzuki, Isuzu, and Lexus, and their dealers as well as their customers trying to sell used ones were not too happy with CR.
