I have seen plenty of cars not make to 165_000 miles, those that do are often near the end of their life. Mine is beat and barely holding together and it is at 97_000 miles.
Ironically, more modern cars will probably not last as long! I can rebuild just about anything on this car, electronics included (most complicated part is perhaps a common opamp). On modern cars, as soon as the advanced ICs (say an ECU) are NLA you’re SOL.
It's only the few that were both made better, with no production flaws, and great maintenance that have lasted long enough for us to see then with 150k miles before being purchased today.
My car is at 350 000 km now, and I'm not planning on selling it anytime soon. It doesn't have any special problem, except for a malfunctioning electric window lifter on one side. It's only one data point of course.
There is some percentage of cars crashed in the first week. It only takes a few of these to cancel out the average of extreme outliers like your car.
For reference I have never seen an odometer with more than 200 000 on it before. Even most classic rebuilds I have seen like 69 Corvettes have some high 100K count on them, some event have reset odometers.
If I had not bought my car (it was at 300 000 km) I'm pretty sure it would have been sold in Eastern Europe instead, or maybe Africa since it's a Peugeot (a 406).
In the countryside, it's also very common to have both a nice recent car, and an old reliable one like mine for the dirty work. Most people I know do have one car that is a few 100 000s of km. Also, we mostly use diesel here, and these are supposed to be much more reliable than the gasoline engines used in the US (and I'm not going into the purported lack of reliability of American cars to begin with). I'm talking about everyday cars that are 15 or 20 years old, not classic cars.
Replacement parts on these are also far more expensive. New turbo is a four-figure number just for the part. Injection pumps are bloody expensive, too.
Less optimized designs may also be a factor. CAD and FEM modelling has only become better with time, so back in the day engineers would rather make a more conservative design, nowadays that's not so necessary any more.
Perhaps they don't build them like they used to, but our 1980's Honda sedan also easily clicked over 350,000kms too.
Turns out it has gone round the clock...
There's probably a Youtube video that'll walk you through how to replace it. I replaced the one on the driver's side door of our 2001 Honda Odyssey last year. I think it was like $120-150 (USD) for the part and 3ish hours. I know almost nothing about fixing cars (just generally how to use basic tools), but have used info from forums and (especially) youtube to fix several things like that on our cars.
[EDIT] great thing about the Youtube videos is you can get a good idea of whether it's something you can manage yourself before you tear your car apart.
I have a 2004 Corvette with about 140,000 miles. Stuff breaks, but it is a vette. My last F150 had about 160,000 miles when I, uh, wrecked it. Still looked and drove like new.
'99 Toyota 4Runner, 232K miles (currently own); '85 Honda Civic, 197K miles; '59 VW bus, ~490K miles (with a rebuild of the 40hp engine at ~240K miles and a transaxle from a junker at ~300K miles).
You are ridiculously hard on your capital equipment. It must be nice not to have a care in the world for your expensive possessions. Personally I couldn't bring myself to torture fine machinery like that.
