Mileage Vs. Car Age: Which is More Important When Buying a Used Car?

The debate of mileage vs. age is as old as the auto industry. Each has benefits and costs, and this formula is the key to determining the answer to this debated issue for used car buyers. 

Sometimes, an older car with lower miles is a better choice. However, in others, a newer car with more miles is better. It depends entirely on what you, the buyer, need from your vehicle. With that in mind, let’s get into the cost-benefit formula.

The Cost & Benefit Formula

This formula applies to any vehicle purchase, whether you realize it or not. Effectively, a vehicle is, at its core, a cost. This cost comes with benefits, and whether those benefits outweigh the cost determines the merit of your purchase. 

Now, we’ll break down the formula for age vs. mileage. First, age. The years take a toll on cars, but only if poorly maintained. This is why collector cars with a low odometer and good service history are valuable.

Now, mileage. A car with lots of mileage and a strong service history will function better than a car with 6 miles sitting in a barn and being driven a few feet a month. So, if we apply these factors to the cost-benefit analysis of a vehicle, we reach an interesting conclusion: a balancing act of sorts. 

Maintenance is king and the key to the formula. As long as a strong maintenance history applies, there’s almost no reason to fear an older car or one with some miles.

Mileage can be a blessing.

So, let’s talk about mileage. Those in their lives caution most people to avoid buying a car with too many miles. The logic is that a car with a big number on the dash will be fraught with mechanical peril. In most cases, this logic stands. 

However, some models defy this logic. For example, the Toyota 4Runner. It isn’t uncommon to see these cars surpass 200,000 miles with little to no problems.

Conversely, there are cars where this logic certainly does make sense. Older sports cars, for example. An old BMW M3 with a string of owners and poor maintenance history is likely a ticking time bomb. Sports cars are often complex, and these older systems will fail rapidly with miles and improper service. This is also true of luxury vehicles.

Older cars are much the same story. Once again, it’s all about the service history for the cost-benefit formula to work out for you. The biggest thing to note is safety. Newer cars are safer, full stop. The human race has come a long way in keeping people from being hurt by automobiles. Once again, if that isn’t as much of a concern for you, add that to the cost-benefit formula.

If you find a car that works well when applied to the formula, it’s a safe buy in most cases. So, in summary, only buy an older car if it’s been well maintained, and the same for a high-mileage car. Use common sense and the tips provided here, and you’ll come out on top.
