Determining what is a good mileage for a used car in km depends on several factors, including the age of the car, the number of owners, and the type of driving it has undergone. Here are some general guidelines to consider:

• Low Mileage: Many automotive experts believe that a used vehicle has "good mileage" if it has been driven less than 160,000 km. However, mileage alone can be misleading, and its important to consider other factors as well.

• Age of the Car: To determine whether a car has reasonable mileage, you can multiply 12,000 by its age. For example, good mileage for a car thats 5 years old is 60,000 km.

• Number of Owners: If a car is 10 years old and only has 90,000 km on it, mileage alone indicates that it could be a good deal. However, if it has had four owners during that 10-year span, theres a strong possibility that at least one of the owners didnt properly maintain the vehicle.

• Type of Driving: Certain driving conditions are rougher on cars than others, and this can affect the cars overall condition. For example, a car that has been driven mainly on highways may have less wear and tear than one that has been driven mainly in stop-and-go traffic.

Ultimately, there is no definitive answer on how many kilometers on a car is too much, and mileage is just one factor to consider when buying a used car. Its important to also check the cars maintenance records, get a vehicle history report, and have a trusted mechanic inspect the car before making a purchase.
