Ages ago, it seemed like 100k miles was the 'aging point' of a car, either some type of milestone or a warning to start searching for something new.
As engineering gets better though, it seems like that's not the case. 100k miles nowadays seems like nothing for a car, I have a 2001 Buick Regal that's more than likely got 200k+ on it (dead digital odometer), and runs fine other than some minor quirks that seem to build up when driving a great running car (powertrain-wise) for years on end.
As I would like to get these 'quirks' taken care of, it got me thinking about how long I should expect my car to actually last.
I wanted to ask a question that wasn't too broad, but wasn't too specific to just my car, because that's impossible to answer. Well maintained cars manufactured during the 2000s could probably be grouped together in terms of life expectancy. And to define 'death', I'm referring to either the engine or transmission needing complete rebuild or replacement. driveshafts and rear wheel differentials seem like moderately priced components in comparison, but I could be wrong.
I also mentioned that this is a 4 season climate, in case that makes a difference. I purchased it from a southern state, but it's been up here for almost 8 years now. A little rust has appeared but nothing that appears to be too intense.
I see a related question, but I don't think it's a duplicate, but I could be wrong.
Not looking for Guinness World Records or anything, I've seen stories of Ford 1/2/350s topping a million miles, but I've also worked at Ford and seen what goes into those specific models.
So, to bring it home, should one even consider an 'aging point' of a car anymore, when determining whether to repair or replace, or just celebrate a milestone?
