8 years is considering that you drive 20,000 miles a year and that the car will break down at 150,000.
The vast majority of modern cars of decent quality can easily go ~250,000 miles, and I’ve rarely ever met anyone that’s driven more then 10,000 miles a year.
That means you can probably squeeze a good 15-20 years out of a modern car based on how well you take care of it and how much you drive.
Depends on the brand as well. Most Japanese cars I see my friends and family with usually work 20+ years.
There is a reason warlords and ISIS use Toyota trucks. I’m pretty sure you could run those over with a tank and they would still run fine for 400k miles.
The Japanese car in our family is an absolute workhorse that was driving 15k a year and it is still going strong 16 years into its life with 250k miles.
Honda too. A lot of people I know swear by their cars. They have a couple plants in the US, and they seem to treat their workers fairly decently -- by capitalist standards, of course, which are a very low benchmark.
Plus, the Trabant was just better-looking (I hate that stupid Steve Jobs minimalist de-industrialized aesthetic that's everywhere these days)
