Most people try to find a used car with low mileage. Low mileage means less wear and tear on the overall vehicle. Few people are going to consider purchasing a 1992 Dodge Shadow with 250,000 miles on it. A Mercedes Benz with 250,000 miles on the odometer is still a good deal, especially if it is a diesel. These cars are known for reaching 500,000 miles and more with few problems.
Routine maintenance is always a factor.
A car that is not taken care of will be lucky to make it to 50,000 miles. Many car manufacturers like to recognize cars that have reached certain mileage milestones. Mercedes Benz offers a beautiful gold grill badge when your MB reaches 250,000 km or 150,000 miles. You can then apply for a badge every additional 250,000 km. When your odometer hits 200,000, mileage becomes fun.
