I can appreciate him choosing the Sol GXP over the MX5... but if value comes into play at all, I think he's remiss in neglecting the Mazda.
As for the Impala SS... I've been in the new Pontiac twin to the SS (The Grand Prix GXP) and found the power impressive. And it's a well-equipped car for the moolah too. However, to have this car make the list before a Hemi Charger or more surprisingly, the Mustang GT, is just silliness. If the Stang doesn't make part II of the list, there's something seriously wrong there.
RSX-S would be on my list too Marc... but with the Civic Si already included, I'd say that base is essentially covered.
