Heck, I'm wondering why the used a Touring 350Z instead of the Track model. According to C&D's own numbers, the Track Z is .4 second faster to 60 than the heavier Touring trim. They even mention that the Brembo brakes on the Track model would have been beneficial in this test, but that the Track model is more expensive. However, the Track is still way under the apparent threshold of $40K, so...
Same for the Mustang... the MUCH faster Cobra is well under $40K, but they went with the Mach 1. Why set a price threshold and then basically ignore it?
Plus they harp on the S2000's cabin noise... wtf do they expect? It's a convertible, the others aren't. Sure, the S2000 is inherently loud, but you can't just slap a hardtop on it and start comparing it to coupes.
All in all a rather motley crew for a comparo IMO. If you're doing a performance-based test, at least get the best-performing trim of each vehicle you're testing.
