Hi I just got my new Sentra 1.8 S Special Edition on Monday. It is Radium and has the sports apearence package and the Fosgate 300 watt system. So far I love it! The only thing I got for it so far is some cool Chrome Sentra licence plate holders I ordered fro E-Bay for $ 5.00 a piece. I will be looking to add a CAI and an exhaust kit if they are available for this car. Look forward to chatting with you fellow Sentra owners in the future!
