“IN 2004 MY MOM BOUGHT A NEW 2004 FORD MUSTANG WITH THE 3.9 V-6 MOTOR AND WITHIN A COUPLE OF MONTHS IT STARTED TICKING REAL LOUD WHEN YOU FIRST START IT UP. COME TO FIND OUT IT WAS A PASSENGER SIDE EXHAUST LEAK THAT JUST GOT WORSE, AND AT THE SAME TIME HER ENGINE STARTED MAKING LOUD CHIRPING AND CRAZY NOISES TO FIND OUT IT WAS THE CAM POSITIONING SENSOR THAT WENT OUT. WELL SHE PAID ABOUT $550.00 TO GET THE SENSOR FIXED BUT SHE COULDN'T AFFORD THE EXHAUST TO.SO STILL TO THIS DAY SHE DRIVES HER NICE LOOKING MUSTANG CAREFULLY AROUND TOWN THAT SOUNDS LIKE ITS READY TO DIE, AND I WOULDN'T TRUST DRIVING THAT THING 10 MILES OUT OF TOWN. IT MIGHT NOT BE AN EYE SORE BUT IT SURE IS AN EAR SORE, AND IS STRESSING YEARS OFF MY OLD BROKE MOTHERS LIFE. WE'VE ALWAYS BEEN A FORD FAMILY AND MY DAD RETIRED FROM FORD PROVING GROUNDS. BUT THAT IS THE SORRIEST FORD WE'VE EVER SEEN.OH YEAH, PLUS THE AUTOMATIC TRANSMISSION NEVER SHIFTED RIGHT FROM DAY 1, AND SHE HAS HAD TO REPLACE THE ALTERNATOR, BATTERY ,A PULLEY, THE SERPENTINE BELT ETC.AND IT HAS A LOT OF RATTLES AND ROAD NOISE,AND IT JUST BARELY MADE 60,000 MILES. *TR”
