Soo you got two tests. One with manual and the other with auto and both are low 13's at over 107 mph, on a typical unprepped non 1/4 track surface, and you still dont think this car has a probable 12.9 in it on a prepped track? All it has to do is knock out a good 60' time. 108-110 mph can be enough to hit a 12.9 if you kill the 60'. It may take one hell of a launch but its at least "possible" imho. But until its done cant really disregard what you have said either. I guess time will ultimately tell.
BTW you have Sport/Touring and auto. Maybe that little extra weight cost you a few 10ths? Maybe?
Car in this test I believe only had the sport package I believe and I have no idea what the da was where they ran.
