I was having my oil changed and my mechanic told me that my Pontiac G6 needs a new catalytic converter. He also said it’s going to cost $1,700! I’m worried that he’s just trying to squeeze more money out of me. Is that a fair price for that job? And whatever is a catalytic converter? Is it really that important?
