I would first like to say that i have seen spy photos and the car looks like its coming along beautifully. BUT PLEASE FOR DON'T SKIMP IT ON HORSEPOWER. Please give it at least 290. All its leading competitors are playing in the same area. Give it a dual intake plenium.
Please put rear air conditioning vents in the '08 CTS. This feature has been missing in the current one, and is the reason why I have not bought a CTS to replace my Catera. I would prefer a CTS over an Infiniti G35, but only if it has rear vents.
