Never take it through a car wash with rotating brushes or use anything that will damage your clear coat. Never wipe when dry or lean on or sit on your car. This goes for all cars.
You are going to love your Neon srt4. I still love mine after almost 2 years now. Get a stage one and the AFE airfilter or K&N airfilter and you will be happy. Also get rid of those narrow 17x6 wheels for at least something 7.5 inch to 8 inches wide with stickier tires.
You already have the Quaife torque sensing differential.
