Listen, the Mustang is a great car for the price (wow, those 2015's optioned out mid 40's, ouch), but even the PP versions have their limits.
My 2014 GT/CS is a cruiser, handles great for DD, but a track star it is not. I remember back to 1985 when I purchased my new 1985 Mustang GT, I thought I was on top of the world....until my ego got smashed and balls handed to me by a 1986 Fiero GT on the roads of the Hocking Hills in Fairfield County, Ohio. Even the SVO's couldn't out handle those Fiero GT's, especially the 1988 version with suspension co-designed with Lotus.
That Fiero opened my eyes to the fact that I truly was: "a legend in my own mind."
When it comes to handling, the Z28's, Porsche's, and Corvettes rule the road......unless you got a huge bank account to work with. If I had $100,000 burning a hole in my pocket, I'd be down at Chevy getting one of those Corvette Stingray Z06's.
