R/T vs SS. You post a supercharged mustang: off topic. Rant about the corporation: off topic. Rant about your dealership experience: off topic Rant about your junk '85 Laser: off topic. Never mind.....

Their tests should have more consistent drivers to eliminate some of the driver error from affecting the test. Some people are better getting the launch than others. I would think that you wouldn't want that to skew the test.
You don't even specify if you want data from an auto or manual trans car, or what trans the SS had. If you want a comparison, you must do a fair comparison and make it apples-to-apples.
