Holden's super muscle cars. 301 upgrades over the Commodore SS. Both pack the LS2 with 411hp/405ft-lbs, your choice of a six-speed manual or automatic, and many luxury features. They hit 60mph in 4.9 seconds and will never see the light of day here. HSV Clubsport R8 - 19s HSV GTS - 20s They'd look good wearing Pontiac badges (they already have a split grille), especially the GTS.
