A Toyota will last twice as long as an American car at ay price point. I've traded in or sold several with perfectly running engines and transmissions over 200,000 miles. American cars may be made to go 100K now compared to 60K in the 80s, but if you change the fluids Toyota engines are basically immortal.
Engines? An engine is a small part of a car today. When all the electronics break; the car becomes worthless.
Also in terms of larger vehicles; anything with a Chevy V8 basically lasts forever. Lots of trucks on the market with 350-400k miles still going on the original engine and many with original transmissions. However Transmissions can be overhauled for those vehicles for around $500 so it is easy to keep them running literally forever.
I am also not sure where the sentiment of 60k miles in the 80s comes from, shows that you have literally no basis in reality. American vehicles started to go down significantly in quality in the early 90s until the market collapsed in the mid 2000s with vehicles engineered to fail after 80 or 100k miles with things like head gaskets (like my fathers 2001 Malibu with a head gasket that would degrade sometime between 80-100k miles, causing a very expensive repair that would cause most people to sell their car rather than fix it).
However my Father drove his Malibu until 267k (when it was totaled due to a Prius with no working lights on it) on all original parts outside of the head gaskets and alternator. Nothing else ever failed. he never changed the transmission fluid and it still shifted like butter. Still got over 30mpg with a 3100 V6. Honestly he never even changed a coolant line, ignition coil, o2 sensor, cat.... literally nothing.
Then he bought a second one but with all the options and all the electronics in the car failed (his first one was a base model with manual windows and only a radio) and he ended up selling it due to him being upset about replacing the window regulators and fixing the stereo all the time.
I have a Chevy Cruze 2014 1.4 Turbo and on the Cruze forums there are several cars with 200k+ on original engine and transmissions with just basic maintenance done + a few sensors that are known to go bad routinely. Most of the turbo models though do have a turbo that has been replaced by that mileage. Mine I have only had for 1 year and I don't know about the transmission lasting that long. I think the previous owner didn't take that great of care of the engine/transmission in general. Even though the engine runs quite well the transmission makes some concerning noises sometimes (manual) and the turbo Wastegate is rusted (car came from the Rust belt I found out) so I will need to change it. However it drives quite well and overall hasn't actually broken down on us in the ~16k we have put on it since purchase.
I have a Infiniti G35 2004 and it has 208k miles. Cats failed at 160k, O2 sensor failed a second time around 180k. Transmission failed fully by 180k. Rear main seal failed around 165k... Suspension was completely shot around the 175k mark... I bought it at 158k (10 years ago in June) in need of a little work but in overall good condition. The owner thought the head gaskets were acting up but it was actually the coolant system having air in it. While it is a super fun car and I personally love the first gen G35's it shows that Japanese cars (even great ones like the G35) aren't just infalliable. My car's audio system also broke over time with the CD Changer being broken when I bought it by only playing out of some of the speakers... the XM Radio died in it as well over the last few years and the window regulators went bad and the rear interior side panels started to unglue and deform themselves.
I spent over $10000 (which is more than double I paid for it) restoring it, replacing wheels and repainting it, redoing the interior, etc.
I have a 2011 QX56 (QX80) and it has 150k Miles today. I bought it with 80k 7 years ago. Overall it has a been very reliable. However I have had the alternator fail twice, had a charging issue that killed 2 batteries, and had the ignition coils blow out at 138k and kill one of the cats (died on the highway nowhere near the destination so had to be limped to location). The engine also was filled with carbon and we did our best to de-carbonize it (at 144k when the starter died) despite me doing a carbon Cleaning (CRC-IVD treatment) on the truck every time before I changed the oil. As well as a seafoam treatment to loosen the carbon. Otherwise the engine wouldn't have lasted much longer as the ports had literally more than 1" of carbon build up per port.
My first car was a Honda Civic 1997 and when I bought it; it was just turning 11. Had 147k miles and was in good overall condition. In the first year of owning it; the O2 sensor failed, coolant sensor failed, water pump failed, transmission started to fail (automatic). I ended up building a new engine, swapping it to manual and modding it with a turbo. Drove it like that for years and today its a "race car" only. Soon when I finish it; I expect to make around 650WHP on the original engine that came in the car but built for boost.
My 2017 Chevy SS hasn't had any problems in the 6 years that I have it. I modded it with a P-1X Procharger in the first 8000 miles; it now has just rolled 40k. No issues, other than me breaking the Procharger belt one time (which isn't the car itself). Even after a horrible accident that I lost all 4 doors; the entire car still works completely fine. Although I do have a stupid error about the battery being low every time I get in the car (it isn't low) that I will eventually probably replace the entire battery fuse box to hopefully fix. I also broke the reverse lockout solenoid wiring while racing the car, but I can't blame GM (Holden) for that.... despite the car being almost totaled and rebuilt literally everything works after now 6 years of ownership. The car is built extremely well and proved that in the accident. Definitely one of the best cars that GM and its subsidiaries have ever produced.
My last Vehicle is a 2006 Nissan Titan LE Towing Package. 120k Miles, 1 Owner, well taken care of. After buying it the Caliper stuck in the front and ruined the brakes, then the brake booster died a few months later. It is a known issue with these trucks. Now one of the bed shocks died (it is 17 Y old though) and the valve covers leak a bit of oil (again 17Y old and parked near the beach for years). Otherwise it has been great to us in the past couple years of ownership.
At my old job one of the guys had a brand new Prius and it kept having issues with the TPMS sensors and also an air intake sensor that he had it in a dealer like 5 times during the time he was with the company. The company also bought 3x Corollas for us to use as company vehicles to go to meetings and other travel (and also for the CEO and other board members when they flew into town). The cars all had Air intake sensor issues (IAT) one of them had a Throttle problem and had to go through a recall.. Right before I left the company one of them broke down with a coolant issue... 3 Corollas and 3 with problems.
The moral of the story is that not every car from a specific brand is terrible and not every car from a specific brand is good. Japanese cars are definitely good but there are also problems with them. One of my close friend has a fleet of Toyotas (MR2 Gen1, 2x Land Cruisers, MK4 Supra, is300, LX570) and they have all had their issues. From failing AC Condensors that required a full dashboard removal to transmission issues to other random electrical problems with windows and radios and such.
Do research on a per-car basis and avoid buying first model years of any cars that come out.
