Mileage expectations on used cars. Where can I find them

Shopping for 7 passenger used vehicle and would like to find reference for average milege accumulation before engine problems erupt. Is this possible?

Mary- the average range for "normal" mileage on used cars varies from 10-15,000 miles per year. Time is more important than mileage, along with the overall condition of the car and the service history/records. Yes, most cars can easily go 200,000 miles, sometimes more. I've generally found that Asian cars age more gracefully than domestic vehicles. Good luck.
