Welcome to the family!!
I have a 2008 tC as well. I think what you can do first to your car is start with small modifications that are budget friendly. For example, changing your shift knob, plasti dip your wheels, change your long stock antenna to a short cool one (make sure its sturdy or else it will break off especially in the winter time). If you don't have a specific budget I would just try to get modifications that would help you such as HID's, good performance brakes, performance battery such as Optima, or event tint. But these are couple of hundreds of dollars.
If you have any questions feel free to ask the community or myself. Hope to become friends with you as well
