The average car can last between 200,000 to 300,000 miles if well cared for.
However most people trade in their used car before 200,000 to 300,000 miles is ever reached on the odometer.
Lets say the average person drives 12,000 miles per year so in 10 years the would rack up 120,000 miles on their car.
Most people who have the money trade in their car within 10 years and sometimes sooner.
There are some people though who drive more than 12,000 miles per year and may put on 240,000 miles in 10 years.
If the car has 160,000 miles or less on it then it's likely a good car and can go at least another 100,000 or so miles.
