Tbh this is my favorite era for Mustangs since the 60s. Although I have to give props to the 2011/2012s, which were a perfect mix of old and new styles and ushered in this current generation.
The mid-2000s Mustangs left a lot to be desired and legitimately LOOKED cheap. The obnoxiously prominent spoilers really killed them for me and they looked too much like a slightly improved-upon Mazda rx8 or a Pontiac Grand Prix. Now maybe that's merely my association between them and tacky California Asians, but they just don't look good to me at all. Never have.
I feel like the only people who could honestly favor the type of Mustang in the OP are the ones who have an emotional attachment to the era rather than the style. Like they just got their license and/or went to/graduated high school in 02-06 and that's what all the cool dudes drove. Otherwise, I just don't see what their is to like..
