Sometime it’s just depend on whether you can still find the part or not, and sometime the part is badly engineered that when it break, it can’t be repaired, and when replacement part can’t be found or there’s only low quality one in the market, then it’s time to let the car die. I still fix car from the early to mid 90s from time to time, they all relies on cheaply-made or used part to survive.
