You rented Mustangs - you've
You rented Mustangs - you've not driven a GT, if you did you wouldn't say it doesn't have a personality. I've had a GT with a manual and that car has all the personality a car needs. I've rented the convertible 4 pot,I honestly loved the convertible 4 cylinder, sure it lacks the V8, it also takes away temptation I don't always need under my right foot. In my opinion the top line interiors in the Mustang these day is perfect everything is intuitive, right where you need and that back seat is surprisingly useful. As far as the Camaro - yeah all those things are too, it's a great track car sure, for those of that that don't track a car it's terrible at just about everything day to day.
As far as the Challenger goes - I've never been in one, I'll take your word for it.
