A good mileage for a used car generally depends on the car's age and average annual mileage, which is typically around 10,000 to 12,000 miles per year. To gauge if a used car has good mileage, multiply the car's age by this average. For example, a 5-year-old car with about 50,000 to 60,000 miles is considered to have good mileage

. More specifically:

• In the UK, the average annual mileage is about 7,400 to 10,000 miles, so a 5-year-old car with under 50,000 miles is good mileage

• In the US, 10,000 to 12,000 miles per year is typical, so a 5-year-old car with 50,000 to 60,000 miles fits well within good mileage

• Some sources use 12,000 miles per year as a benchmark, so a 5-year-old car with up to 60,000 miles is acceptable

Cars with mileage significantly above these averages might be considered high mileage, but well-maintained vehicles can still be reliable even with over 100,000 miles, especially brands known for longevity like Toyota and Honda

. In summary, a good used car mileage is roughly:

• Around 7,500 to 10,000 miles per year of the car's age (e.g., 50,000 miles for a 5-year-old car in the UK)
• Or 10,000 to 12,000 miles per year in the US context (e.g., 60,000 miles for a 5-year-old car)

Always consider maintenance history and condition alongside mileage for the best assessment
