Last I checked, the only Mustang with an 'enhanced' engine sound for the interior via electronic fakery is the EcoBoost. The 5.0s use an 'induction sound tube' which is basically a plastic pipe that is attached at the intake tube and firewall (on the 2011-2014s, the 2015s looks a bit different), with a pair of foam baffles inside either end.

I thought the interior in my 2011 5.0 was a bit too quiet for my tastes, so I pulled the tube out a couple of minutes after I came home from the dealership, yanked out the baffles and reinstalled it, and after a quick drive around the block, was much more satisfied with the engine sound from the interior.

Although I wouldn't personally buy one, I don't find anything wrong with an easily tunable turbo four-banger that cranks out 310hp and 320lb/ft in factory trim, and it's worlds apart from the laughable (SVO excluded) 2.3L that didn't even break the double digits in horsepower until the 90s (and don't forget there was a time you could find an sub-100hp Iron Duke under the hood of quite a few Camaros and Firebirds back in the 80s as well)...

Aesthetically, I think a '15 GT with Performance Package and in a darker color (Guard green, Magnetic gray or Ruby Red) looks very sleek overall; I think the headlights and front grille could have been done better (and hopefully in a mid-cycle refresh they will be), but it isn't on such a level that turns me off on the car overall, and had it not been for Ford screwing me over on a customer service level, I might very well have had one in my garage now instead of my Challenger.
