I'd agree on the blue stripes on white Shelby's, the BRG Aston's as well as Jaguar's F1 livery of the same colour. Viewed when stationary, the detail in the STR F1 livery is pretty good too.
Alot of the V8 Supercar liveries IMO arent that special, but ive always loved the LMS/Orrcon liveries with the integrated GT stripes, as well as other classic themes.
