A Pontiac buddy of mine in Texas bought a new 2003 Mach 1. He's a racer at heart, and definately knows how to shift (he also has an 11 second street driven Firebird). He bolted on a set of Nitto drag radials onto his new Mach 1, and hit a 12.99 @ 106.2 mph in some good air. At first I thought it wasn't that big a deal, because Z06's and Vipers are quicker, plus he had to do it on drag radials. But when you sit back and realize that for around $25K, the guy has a brand new, warrantied car, that's a solid low 13 second daily driver.
Cheaper than a new GTO, and in my opinion, the Mach 1 really looks like a modern day Musclecar. Gotta love that shaker scoop...
