I think it's slowly but surely becoming common knowledge now that the Fords are faster, like for like (xr6 vs sv6, xr6t vs ss/hsv, gs vs hsv, gt vs gts??). It would be SO painful for Holedung owners to admit it after them claiming to be the faster brand for so long, magazines claiming ridiculous times, inaccurate kW badges... etc.
I have pulled up along side a fair few HSV's and Holdens, and no one wants to go. You'll get the odd crackhead bogan dreamer in a bucket of **** tailgating and trying though. I had one guy keep letting off the brake at the lights nudging forwards as to egg me on, then I took off normally and noticed he sat back with his passenger window down to have a listen. I should've stung it so he could hear the blower whine!
