<prompt> Human: I bought a used car from a dealership about 2 months ago. Its a 2004 Mazda 6 with 96000 miles on it. Anyways, I bought the car and since then I have realized the whole catalytic converter needs to be replaced which is about 3000. I obviously cannot pass e-check without getting this work done and I have checked with multiple mechanics to price check the job and they all agree on the number. To make matters worse the car now overheats, and fast! Like within 30 seconds of the car being turned on. I called the dealership and they said there was a as is and no warranty implied or assumed policies on the agreement when I purchased it. I have to have a car to go to school and work but now Im out a bunch of money and stuck with a pile of junk. Please help me figure out what I can do.EDIT: Its a 6 cylinder 3.0 liter engine. It has three converters actually and all of it needs to go. I had a family friend that is a manger at a local Chevy plant take a look and he said it is a complete mess. I working minimum wage about 2025 hours a week because Im taking 17 credit hours this semester. I didnt take out a loan because I paid it off for about 3000.EDIT: State is Ohio  <response>: Its a 6 cylinder 3.0 liter engine. It has three converters actually and all of it needs to goThe rear converter is not monitored by o2 sensors, thus it can not cause you to fail an emission test unless the emission test is performed by an exhaust gas analyzer sniffer. To my knowledge, no states require a sniffer test anymore as long as all obd2 monitors have run to completion and no codes have set.You didnt say if you were in California or not, and it makes a huge difference. Look here. This is my cost on the manifold converters for your car:Exhaust Manifold with Integrated Catalytic Converter RearDorman Exhaust Manifolds673-837 840.09 CARB Compliant: YesDorman Exhaust Manifolds 674-837 361.36 CARB Compliant: No.See that? Converter for California Car is over double the cost of other 49 sometimes 48, New York is also weird on someFWIW - these are shitty cars. They are essentially a Ford Escape drivetrain thrown into a sedan chassis and they are a real bitch to work on.Finally, state is again important because many states do have consumer protection laws, where even if the dealer doesnt give you a warranty, a large enough mechanical failure 2 months after purchase may be enough to force their hand.
