That sounds like a good deal for the car. There is a deference in things like intakes and exhaust. The thing to remember is "you get what you pay for" so when buying things don't go the cheap route. If it were mine I would stay away from body kits they usually look gauldy. My advice would be buy it lower it put some rims on it and then decide on what kind of performance mods you want to do.
