The 5.7 0-60 time is quoted from the February 1998 issue of Motor Trend. But i'm wondering....they MUST have had brochures for the current model GS right? Didn't it debut fall of '97 as a 98 model? I'm not too sure, but I'm interested in what the original brochures stated the time to be before MT conducted their test. Probably low 6's.
