Help! I recently got my brakes redone and a new battery. Now it’s time for DMV renewal check engine light is on. Mechanic says both thermostat and catalytic converter need to be replaced. He says the cost of parts and labor are more than the value of the car. I recently looked up catalytic converters for this make model- found some as low as $196. Not sure how much labor will be but seems a lot better than figuring out a car payment- I have no budget for a new car, used or leased. He said i migt find a muffler shop who could do it. Any thoughts on whether it’s worth it?
