HEY EVERYBODY, I RECENTLY BOUGHT A USED 1998 FORD EXPEDITION XLT WITH A 4.6 ENGINE. IT HAS A DVD PLAYER IN DASH WITH A NAVIGATION SYSTEM AND XM SYSTEM. 20 INCH RIMS AND TOYO TIRES. ALL INSIDE AUDIO IS PIONEER. VERY NICE. I BOUGHT IT ON EBAY FOR $13K . NICE DEAL FOR MY AREA. MY QUESTION IS WHAT DO I DO NOW??!! I WANT TO CHECK THE CAR BUT NOT SURE WHAT TO CHECK FOR. TUNE UP? WHAT PARTS OR AREAS SHOULD I HAVE THEM CHECK?? AND WHAT DO I NEED TO DO TO MAKE MY EXPEDITION BETTER AND LAST LONGER? ALSO MY OVERHEAD CONSOLE DOES NOT HAVE THE SENSOR THAT READS THE TEMPERATURE, SHOULD I PUT IT IN AND WHERE CAN I FIND IT? ALSO I HAVE ONLY ONE KEY. HOW DO I GET ANOTHER ONE MADE, AND DO I NEED TWO? ALSO I HAVE TWO HOLES ON MY UPPER CONSOLE , IM THINKING FOR VENT BUTTONS FOR THE REAR WINDOWS. IS IT HARD TO PUT THAT IN NOW? AND I WANTED TO PUT IN A REAR FLIP DOWN TV BUT THE REAR OVER HEAD AC IS BLOCKING, ANYWAY TO MOVE IT? I ALSO HAVE A VIPER790XV ALARM, DOES ANYONE KNOW ABOUT THIS ALARM? SO I GUESS THATS IT, IM ALSO LOOKING FOR A EXPEDITION CLUB IN MY AREA OF NY CITY. AND IF ANYONE HAS ANY OPINIONS HOW TO HELP ME ENJOY MY BEAST LET ME KNOW . THANKS!!!
