dude, just do your regular maintenance on the car, and you will be happy. The LS is a fun car to drive, no matter if it is stock or not. If you want a pretty good mod that will increase or enjoyment of the car, just save up about 200-250 $, and get a nice little intake; you'll love the way it sounds when you rev, and you'll feel a considerable difference when you change gears. Other than that, just have fun with it, and save your money !
