When you invest in car repairs (as you have seen) you are paying for one or two years at best. The tipping point is when you would have purchased a lot more time without worrying for the same price.
This doesn't make sense. A car is not an investment. Say you have the choice between a $1200 repair and getting a new $20,000 car for $400 a month. Say the repair gets you a year and then you buy a new car. The comparison of where you are after 3 years is:
(if you did the $1200 repair) -- You've spent $10,800 over three years and now have a 2-year-old car.
(if you didn't do the repair and got a new car instead) -- You've spent $14,400 over three years and have a 3-year-old car.
If repairs can get you one more years, it should be worth it to you if the repairs are less than a year of car payments, discounted by how much you hate your car and want a new car. It isn't really a science.
