How many miles do cars last before they become worthless?

i keep hearing people saying Toyotas and Subarus hold their value and whatnot, yet I owned a Subaru with 250,000 miles and it was a pain to sell(even though it was still in pretty good condition), couldn't find a buyer until I dropped it down to $1000. Everything worked on it and it was reliable.

So is there like a general mileage range where a car becomes "worthless" in a sense that nobody will buy it? If I buy a new car with 0 miles, at what mileage should I sell the car before it is hard to sell? Would it matter between brands(looking at Jeep Renegade, Ford Escape, and a few Toyota models)? 60k miles? 100k miles? 120k miles? 150k?
