I don't know If I would replace with another Mustang, "IF" I were to replace.
I've bought a couple of parts for it. One installed, one in the garage still, waiting to be installed. It's a lot more fun when you add your custom touches to it, whether it be performance or styling.
OP,
what mode are you driving the car in? Normal? If so, give SPORT mode a try, without using the paddles first. It wakes up the car as does turning traction control off and then if you REALLY want to get daring, there is a way to COMPLETELY turn of traction control as well.
