Thanks to the good news on my 04 GT, I'm keeping it until spring, hoping to trade it for a Mach 1. Questions: How reliable are 4V's as stock daily drivers vs a 2V? I know they run a little hotter but what else? Are there 4V-specific issues I should check for on a test drive? Other than that my other option is an early S197 but I would rather not go there. Too many issues with the 05-06 cars I can afford.
