I'm a teenager and my car is a Jeep Wrangler 1991 YJ. I am looking for some good modifications that aren't that expensive (b/c I'm a teenager therefore not much money) and will make the car run better / look better. I know Jeeps are offroaders but I don't have the need or the money for a lift kit or a winch. Any ideas? Like good dash interior or lighting parts? At this point I'm more concerned about it's functionality as a car than it's functionality as an offroad vehicle.
