I went with a GT package and so far, I am really glad I did. I am generally not one to go all out on modding a car so putting in an aftermarket HID set or even a full stereo setup isn't something I was interested in doing.
I think it's funny that people have referred to how "abysmal" or any similar adjective to describe certain parts of this car. Sure, some parts aren't top of the line but we're not talking about a Benz or any other high end brand here.
As for the seats not being fully leather, this is actually a major plus since if it were, you would slide around a lot more.
I am planning on putting in a better than average amp and sub in the trunk to enhance the stereo which will allow more power to the slightly better than average Bose up front.
When it comes to the HID lights and the rain sensing wipers, personally, I think this feature is pretty cool (burnout) I live in FL so it can rain and then be sunny about five times on my way home from work which takes about 50 minutes each way. To me, the sensitivety is just right at +2. The HID lights not only look great on the car but work pretty well on the 0 setting when driving at night.
If I were to do it all over again, yes, I would still pick the GT....it would even help the resale value as well.
