I agree w/ deuce, we'd all love to really see how the CLS' do. There's a guy, Silverbullet on acura-cl.com who claims he's undefeated in 12 runs vs 4.6 and 5.0 stangs.......he's n/a, but he's got a CAI.
Maybe their hp rating (260 @the flyweel w/ 3400 lbs), is a moddest claim.
They're very nice cars, but 12-0 seems a tad outrageous.
