you could start off cheap by just painting ur tailights or turn signals or whatever you want. Then just for an enginge mod, put in an intake. Put new rims, but nothing ricey. If you get bigger rims, then you have to lower it, otherwise it will look like ur going offroading, and u'll get horrible body roll. Fog lights are fairly cheap if you do ur own labor. And if you do anything to it, you ahve to first make sure your car isn't going to break down in 2,000 miles, so do all maintenance, depending on current mileage.
