<prompt> Human: I have 2008 Mazda 6 with 158,000 miles on it. I paid too much for it when I bought it and Im pretty upside down on it I know, thats on me. Anyway, without getting into details on the issue Catalytic converter replacement, Ive been quoted a fix at 2k that is needed to pass emissions in July. I have no warranty or anything to help cover the cost. Anyway - Im scared that if I bite the bullet and spend the 2k on the repair, there will be more issues down the road from how high the mileage is. It also seems like its not a smart idea to spend that much when the car is worth only a little more.Is the better option to roll the negative equity of the Loan into a newer car not brand new? This will obviously cost me more monthly but will be less risk of future repairs being needed. Is there an option Im not even thinking about?  <response>: I can get a brand new catted downpipe for 299. You are getting played hard.
