took the ranger in to my local ford dealer yesterday afternoon to have the srs light on the dash looked at, and hopefully, repaired. while i was waiting in the lounge area drinking their coffee, i struck up a conversation with a nice looking lady that had brought her mercury mountaineer in. at this point the service adviser advised me my little truck needed a sensor replaced at a cost of $245 parts and labor. i told him to fix it already. thought i was getting hosed, but it's a safety related issue and i have little to no experience working on srs systems. a few minutes later the same adviser comes in and tells my new found friend that it was going to cost $465 to have the alternator replaced on her mercury! i thought holy smokes, they're taking her to the cleaner's. he then went on to advise her that the cause of her check engine light was due to bad O2 sensor's, caused by a clogged catalytic converter. he told her (get this) $3000 to replace the converter! she was almost in tears. i felt bad for her so i gave her my phone number and told her to go to NAPA and get an alternator and i would install it for her. do catalytic converter's really cost THAT much? i know what i would do if it were mine.
