LOL. I have many times. Not impressed for the money they are. I'll take my pulled cobra any day of the week over one. Got Less than $30K in that car and it's got 500 to the ground, handles like it's on rails and stops on a dime.
I wont argue that the mustang is not known for handling but they do just fine with some simple mods. Also, keep in mind my 04 cobra is a factory IRS with a factory supercharger that was WAY overbuilt (minus the IRS pumpkin).
If you want a car that can go around a corner go get a Miata. Had one for 11 years and it was by far the best car I've driven when it comes to handling corners. Not a real manly car though.
Now for the ZL1. I've driven one and was impressed with the performance. I do believe it beat the GT500 to even though it has less power. These days their are a lot of great cars out there. No need to be a brand snob anymore as if you do you'll miss out on some great cars.
