GM F-Body FTW. I have a Z28 as well, but I have been more than impressed with the latest Mustangs. Around here everyone in a Mustang is kind of a tool though, and that's why I avoid them. Every region is different though. My Camaro is a 2000, so it's not as refined as new cars, but I've driven Mustangs too, and the biggest thing you'll see in the Subaru (WRX OR STi) is a sense of roundedness. I have to say that the scream of a V8 at redline is something you won't want to lose, so I'm glad to see you keeping at least one for the track/weekends. There are lots of threads that discuss the benefit of an STi over a WRX, but it all comes down to you. I have had 2 WRX's as DD's but in the end upgraded to an STi for those additional benefits. If you're the type that will spend a little extra now to not have to do it later, get the STi. IMO, you can't really compare a muscle car to these cars. They really are SO MUCH different. I do feel like the Subarus are more complete feeling. There's less of that raw feeling, but they feel like an all around performer and good in every way. That's the only way I can think of comparing the 2. I prefer the STi, but I reeally don't mind taking the T-Tops off the Z28 and cruising around in a bit either. Having both is the best solution.
