Hi - I have a 2004 Convertible with a Supercharged LS1 - I love the car with all the power. But I believe in keeping a car as original as possible. I am no longer a speed demon, like I was as a kid. My son likes to push it. I Just enjoy cruising. I like them the way they were built. I would recommend in keeping the car stock and upgrade to a newer one. If you are looking for more power. I will never sell mine. I will leave it to my Granddaughter. But if you are looking to sell, I might be interested. I like them stock. Just my opinion. Rich
