<prompt> Human: So I have this 2010 corolla 70k, paid in full, clean title. Very well maintained, never missed a scheduled service, all done at reputable shops. Everything was super duper until this latest service appointment when I found out that apparently the car is falling apart Timing Cover Reseal including crank seal, tensioner o-ring, oil filter housing seal, and water pump replacement along with excessive rear tire feathering. All in all, it would cost around 3000 to fix everything aside from the wheel alignment issue. Initially I thought that the shop is trying to scam me so I went to an independent mechanic and I just told him to do a full inspection and he came up with around the same estimate..Disregarding the fact that Im a little pissed because I choose this particular car to not have to deal with this crap and I really tried to do my job by maintaining it properly, now I want to get rid of it.KBB tells me that this car is now worth 6000 - 8000. A 3000 repair bill is almost 50 of the car in what I assume to be its fixed condition.From a financial standpoint this is really the only thing I care about in this scenario would it make sense to fix it? I tend to no as the last repair would need the engine taken apart and Im not sure how much money Id have to invest in it in the following years just to have it run properly.I was reading online that the rule of thumb would be that if the repair cost is larger than 50 of the car or larger than a year worth of payment for a new car, repair is a no-go.Would trying to have the dealer buy it back or trader-in for a new model be a better idea?I know it would be bad initially from a financial perspective but Im thinking about long term cost of ownership. I paid around 17.000 for it and until this day I will reach 22.000 for this car, at around 3666 per year or 0.31mile.A new car would have at least 5 years warranty but would set me back around 18k - tradein value probably around 4000.Im trying to avoid the sunken cost fallacy by asking for different opinions..EDIT: Thanks everyone for the answers. I will most likely keep it and further care for it. Ill go ahead and put a board under the car to see how much it leaks if any and find a 3rd opinionquote, after I fix the alignment and change the tires. You people have changed my perspective on cost of ownership. Thank you.Assistant: Where are you located? I live in a rural area about an hour outside of any major cities. I had a breakdown with my Hyundai and the shop I had it towed to only charged me 50hr whereas any other shop would charge upwards of 80-100hr. Human: Yeah, it may have something to do with that. I live in Seattle.  <response>: Take your car to KS in Bellevue. I used them for years until I moved away and I cant find a new mechanic that is half as good as those guys. They are the best and so reasonable!
