The NEW Cobalt SS TC is a great car. But GM went through a spell where they were slapping SS on every car and they tarnished the nameplate.
I believe you're talking about the Sport Trac Adrenalin with the body-kit comment. It was great in concept, now it is a body kit, but guess what, its not badged as an SVT; that's bc SVT is reserved for serious vehicles.
SVT has not been tarnished, it just hasn't been used much. It's still alive with the GT500, and it could find a home in the F150, F100, Fiesta, Focus, Fusion. But really, a car or two and a truck for SVT is plenty. High hp is not enough for SVT, it needs to be an all around performance vehicle.
