Cherry1809,
as your car has more power and torque, and better suspension, than a standard Aero, why do you want to change it? You would only end up having to spend more money on it to make it as good as your car is now! The only better things you would get are the wheels, which are available if you keep looking (I've just got some!), the seats (but do you really need more than the driver's seat? I think the Aero rear seats are a disadvantage), and the body kit, which is a matter of personal taste. The CSE has the nicer dash board.
Why change a car which you know (and probably isn't worth that much) for something that you don't know, isn't as good, and costs a lot more?
I had the same dilemma when I found an Abboted Aero for sale. It was nice, but no better than my car, needed the brakes upgrading and just wasn't worth twice what I could sell mine for.
