I've had my '03 PT since August of 2004. I bought a new house last year so I haven't had much money to put into it like I have my other cars in the past back when I was single and responsibility free. But I have put some money into it. I have a JVC touch screen cd/mp3 player. I just put a JVC 12 disc CD changer under the driver seat. I have 2 12" Rockford Punches with a PPI 600w amp which isn't much power but enough bump and bob ya head to. I put chrome pillar strips on the windows. I just put on new clear/chrome euro tail lights with 18-LED light bulbs in them. I have 2 green neon lights inside the vehicle, 1 mounted on top of my speaker box and 1 mounted above the center console. I have 2 tiny green LED lights installed under the center console. I put green tinted head light and fog light bulbs which give off a nice effect. I just had my front windows tinted to match the factory rear windows as well as the tinted sun strip on the windshield. I got a "PT CRUISER" silver glitter decal above the front windshield and I got my 3rd brake light cover to say "CRUISER" when I brake. I have many more ideas to purchase in the future so look for updates and new pics once I install my new items!
