Welcome to FBO! I have to agree that with the $200 you're planning on spending on mods...I'd do a full tune-up on the car first thing. Reason being is that it may run like a top, but you don't know when it was last serviced. Buying the car is an investment and it'd be a shame if you spent the money to by the car and then something mess up that could have been prevented by performing a simple tune-up. Tune-up = new wires, distributor cap, plug wires, ignition coil, air filter, oil, and oil filter. Those are just the basics. You can also change the transmission fluid and filter as well as flush and service the cooling system. You'd be suprised what changing out this stuff can do for you. Good luck with the Camaro.
