Costomizing my '98 ES

So I went out and got a '98 ES with a 3.2, and I was wondering if anyone had any reccomendations on modifications to make. I'm only gonna spend about 2 and a half right now, so I'm rather limited on what I can do. Thanks for the help ^^

No, I don't want to rice the car out - but I do want it to be more expressive of its driver.
