HEY EVERYBODY IM FROM NYC AND I JUST BOUGHT A 1998 FORD EXPEDITION XLT WITH A 4.6 ENGINE. I BOUGHT IT OFF EBAY AT A GREAT PRICE. FIRST TIME WITH A BIG CAR. I WENT FROM A KIA SPORTAE TO THIS AND I LUV IT SO FAR!!! I WANTED TO ASK A COUPLE OF QUESTIONS. CAN I JOIN ANY CLUBS CLOSE TO ME? WHAT DO I DO NOW?? TUNE UP? CHECK FOR PROBLEM SPOTS OR PARTS? CHANGE, MODIFY? CHIP? EXHAUST? IM LOOKING TO ENHANCE AND MAKE MY EXPY GREAT!!! I BOUGHT IT WITH PIONEER IN DASH DVD,NAVIGATION AND XM SYSTEM, WITH A 12 CD CHANGER. ALSO MY UPPER CONSOLE DOES NOT HAVE THE TEMP SENSOR. I WOULD LIEK TO GET IT, WHERE SHOULD I GO AND HOW DO I INSTALL IT? IM THINKING BRUSHGUARDS BUT NOT SURE? ALSO I ONLY HAVE ONE KEY, WHAT SHOULD I DO AND WHERE? I HAVE A VIPER 790XV ALARM SYSTEM, ANYONE KNOW IF IT?? IT CAME WITH 20 INCH RIMS AND TOYO TIRES. REALLY NICE BUT IM THINKING FOR THE WINTER I SHOULD GET 18" FACTORY RIMS. IF ANYONE CAN HELP ME HOOK UP MY EXPEDITION I WOULD APPRECIATE IT . THANKS
