I'm a hardcore Mustang guy - I've owned ten of them, and I'm only 32. I thought the '05s were ugly as shit when they came out. (still do) To add to that, the '05s were still using the shitty 4.6 motors that didn't make crap for power. When the '10 came out, I thought they looked awesome, but were still crippled by the crappy 4.6 motors. When the '11 came out, I thought to myself "Ford FINALLY did it right after" ... especially after so many years with an anemic motor in the normal GT. I think the '11 and '12 look better than the '13/'14, mostly because I think the '13/'14 have a weird looking front end.
The '15 seems to look cool so far. I'd be thrilled if it drops a bunch of weight too, and no doubt it has an awesome powerplant. Win/Win as far as I can tell.
