The "brand new car" thing isn't a great example either. You can lease a new car for under $100/month which likely has lower insurance costs, is safer, and no maintenance fees other than gas (which you'll also need less of since its probably a more efficient vehicle).

An older car could end up needing several thousands of dollars in repair costs at any time, and maybe more than once. I drive an older car because I could swing a new engine or transmission if it came up. For a lot of people that means they no longer have a car.
