Yeah, it does look like a lot of other cars (The GTO). You certainly won't be mistaking the mustang for anything else though. Ford did an amazing job on the Mustang styling this time. I wasn't fond of the last body-style mustang, but this one makes me drool every time I see it.
I drove one of the V6 mustangs last year (the older bodystyle), it wasn't slow by any means, but I just can't see buying a V6 mustang. That's a car that LOOKS fast and it needs to BE fast. The 6-banger just didn't have the oomph that a performance car should have. That probably changed a bit with the latest model, since they bumped up the horsepower, but I suspect that it's still a bit underpowered to be called a true sportscar. I can understand why people don't get the V8, but it's not something *I* would do. Of course I'm a bit of an oddball, so nothing that I do is "normal"...I mean after all, instead of buying a mustang gt or GTO, I supercharged my sport trac. That whine is cool though and you just can't get that with either the stock GT or GTO.
If I could choose between the Mustang GT and the GTO, the GTO would win, not necessarily because of the styling, but because of the raw power. Now if we're talking Mustang Cobra vs GTO, that's a different story entirely. Cobra...YUMMY!
