My Aunt's Volvo is now trouble free and ready to make its return trip to New Jersey. Thanks very much to Mr Philip Bradley who referred me to his personal mechanic who is absolutely passionate about his craft. He repaired the car, tuned it up and replaced a leaking exhaust gasket for a quarter of what the dealer would have charged. The problem by the way was indeed a disintegrating aftermarket catalytic converter as the dealer diagnosed. Thanks for all the other advise that you guys gave. I do not own a volvo but this is convincing argument to own one. I'll make sure that my Aunt is tuned in. Thanks again keep up the good work.
