I get that the Tahoe and Suburban RST "performance" models with the 6.2/10 speed combo are pretty much Chevy fenders headlights and taillights over a 2018+ Yukon Denali. Other than the fact Chevrolet calls the package a "Rally Sport Truck", there's nothing overly sporty or performance about it. Comparing the "RST" performance package to the SRT's, Cayenne's, X5M's, MB GLE/GLS AMG models out there is like apples and oranges. None of those vehicles compare in overall size to the Tahoe/Suburban platform; hell there's only 2 models amongst those that even come with a 3rd row.
To call it "boy racer" "racer like" or even a "sport" look is somewhat debatable; Let's just call a spade a spade here gentlemen. All Chevrolet is doing is offering a factory option for what a fair amount of forum members are doing themselves to their own rigs after purchase; Swapping out all the chrome trim for items that are black and/or painted to match.
I think it's a clean truck, I'd considering purchasing one in 2-3 years CPO.
