First of all if the car you were looking at was an automatic with "tiptronic" then you were looking at a GT-S. The auto GT did not come with the tiptronic mode.

As far as performance just leave it as be. You are not going to get anything from it that is worth the cash you will spend. It's a fun car to drive so just stick with that and enjoy it.

For looks, wings west has a simple and nice looking kit that is great quality and fitment. Not agressive at all but adds some spice.

I would stick to that. Maybe some nicer rims and a good set of springs and shocks and just leave it.
