The price for performance is exactly why I bought the 14 Mustang GT Premium rather than an SRT Core. SRTs never have cash back, have $1000 gas guzzler tax (in PA, NJ might be $1300) and you get so much more in the Mustang. I had a 2010 R/T and loved it. But when I wanted more performance, it was $32K vs $41K and the Core doesn't have nearly the amenities. And it's a bit too big so parking was always a worry for me. I've driven the SRTs a few times (NJMP and VIR) and they still feel heavy. Awesome ride for cruising the highway and you can fit 5 adults in the car (and maybe 3 bodies in the trunk - it's huge). One other factor was not as much after market support - few vendors with higher prices. That said, if my kids were in college I'd be tempted to trade my DD for an SRT - they just look bad a$$.
