So I have a 2007 Toyota Prius with 285 thousand miles on it. The catalytic converter broke a few days ago and the Prius shop wanted 2500 to fix it. I did some googling and found some new catalytic converters for 150 or so. I asked Toyota about it and they said that they could put the part in and I'd just have to pay for labor, coming out (including the part) to around 500. The mechanic there said that most of these aftermarket parts only last for about 4 months or so, and even then only do the bare minimum. Is this true? And considering the fact that the car has 285,000 miles+ on it would it be worth it to fix it or would something else probably break pretty soon?
Edit: Oh and also would it be possible for me to fix it myself? I don't really have any experience with working on cars, and I don't own any car-specific tools (although I may be able to borrow some). I have built a computer if that means anything in the world of cars (I assume they're both vaguely like a thousand dollar plus dangerous lego set) but yeah. (Although I guess one involves power tools)
