* Annual Mileage: Someone who commutes a long distance daily will have significantly higher mileage than someone who primarily drives for errands. A reasonable average annual mileage is considered to be around 12,000-15,000 miles, but this varies greatly.
* Maintenance: A well-maintained car will generally last longer and have fewer problems, even at higher mileage. Neglecting maintenance can lead to premature wear and tear.
* Driving Conditions: City driving is harder on a car than highway driving. Rough roads and extreme temperatures also contribute to wear.
* Vehicle Type: A car used primarily for city driving will likely accumulate more miles than a vehicle primarily used for long highway trips.
A 2009 car that's 14 years old (as of 2023) might reasonably have anywhere from 168,000 miles (12,000 miles/year) to 210,000 miles (15,000 miles/year) or even more, *if* it's been well-maintained. However, a car with significantly fewer miles might suggest limited use, which could have its own set of potential problems (due to sitting idle). Conversely, a car with significantly *more* miles might suggest a history of harder use or less diligent maintenance.
Ultimately, the ideal mileage depends on the individual car's history and condition. A pre-purchase inspection by a qualified mechanic is crucial to assess a used 2009 car's actual condition regardless of mileage.
