We all know you're a troll when you compare a GT class SCCA World Challenge Volvo to a Grand AM Boss 302R, which is more comparable to the World Challenge GTS class.
Pobst, in the GT class Volvo, took pole at 1:26.361.
The fastest GTS class car, a TSX driven by Pete Cunningham, went 1:33.094.
The fastest 370Z in GTS went 1:37.561. The fastest Mustang in GTS went 1:34.369.
For reference, Joe Foster qualified 4th at 1:36.375 in the Boss onboard you posted of the Conti Challenge qualifying session. Pole that year was by a Camaro GS.R at 1:36.049.
We get it. We know you hate the Mustang and we know you'll do anything you can to disparage it.
Even if it makes you look like a total idiot by posting a World Challenge GT time and comparing it to Conti Challenge GS or World Challenge GTS cars. Sorry, but none of us are dumb enough to buy that comparison.
