At the Track, I've seen STOCK 03 Cobras with excellent drivers do anywhere from 12.6 to 12.8s! Average drivers 13 flat to low 13's.
This car is reported to do 0 - 60 in 4.6 secs and 13 flat on average so if you think it wasn't stock.. think again.. IT IS STOCK!
And on the roll, forget it man... WRXs (unless with the right mods) really get there times from a good launch.. not pulling hard from 60 to 110mph like a Cobra does.
