not much you can do with the big coils on top of each cylinder, though it will be interesting if some company comes up with a better looking valve cover
as if a V8 has never had first model year teething problems. Oh wait nearly every generation of modular did! especially the coyote had plenty of cylinder failure issues in its first year.
ever since the mustang got electric steering it has been praised for its feel, whereas mustangs of the past were not. its kinda funny how ford has been able to do what bmw and porsche have not with electric steering
for some reason there are a few people who bought the 05-09's that think they are the best mustangs since the classics. I know a guy who bought on of the first 05's and when the '10's came out he was the first to say the new interior was horrible and not better than the '05 when it clearly was...
they've pretty much always been only about appearance...
the only things performance wise they ever did were springs/shocks and maybe control arms, and superchargers recently. All of which are parts made by other companies that they slap their name on
