I currently drive a 4Runner. If I had to choose between the new LandCruiser and the Lexus GX, I’d pick the Lexus. Seems like for $70k you get a lot more with the Lexus GX 550 than the LandCruiser standard for $65-70k.
I have not looked at nor driven either one. Perhaps I would not like how they drive. I must be truthful that my driving is mostly paved roads, some dirt roads, and only occasionally something muddy or snowy. I don’t need a TRD Pro or real off-road capability.
