96' Crown Victoria

[96CrownVic]

ok im 14 years old and have a 96' Ford Crown Victoria, and i was wondering what should i do to it? it is a P71 Crown Vic, it was the old reserve police car from my town. we bought it for $200 about 3 years ago and since then have put about 3 grand into it for all the maintence and we had the engine rebuilt and new brakes put on it. we have gotton it up to 135mph. it has no back seat or back door panels. it is a 4.6L V8 auto. so i was thinkin that since most of u know more about cars then i do that u might help me out a bit. if u have any comments or questions, or just tell me what i should do to the car. thanks!
