IMO, there is no GOOD explanation for the fox-body Mustang styling. Now, about '85 or so, they were cheap and fast but the front ends were junk and the intakes needed work. Still, you could get a 5.0 GT for about 15 large and it would run with the Corvette that sold for over twice that price, if not beat it, so doing that work was affordable. I saw guys put 4.11's in the rear ends and crinkle the body panels on them with only minor engine mods. Those 5.0 GT's had scary torque for such a weak unibody and suspension. Personally, I like the '65-'73's and the 2005-present Mustangs - and even then, V8's only! (Probably better look at getting a good used '05 or '06 for a decent price before they screw it up again in 2015...) I don't care how fast a V-6 is; they just don't sound right.
Personally, I really like seeing a strong focus on small V-8 technology, which is what the 289 was, and still is, all about. I enjoy tweaking the small blocks to get what I can out of them for daily driving. Probably my favorite engine block, however, is the Chrysler 318/5.2L, which isn't made anymore. Growing up, I was taken to school in '69 Coronet with a 318; then my second car was a '79 Cordoba with a 318. My grandmother got a new Plymouth Gran Fury (318) in '84, and then my folks got a new Fifth Avenue (318) in '85. Finally, I got my current '99 Ram 5.2L Magnum (still a 318, just better heads than the LA's), and I'll keep this one as long as I can.
