Used car pricing is an elaborate tug-of-war between many different factors, regarding both the condition of the car and the dealer's ability to sell it. When looking at used car prices, you will probably see a range of statistics, such as mileage, service history, and information on the previous owner. These things, in combination with other factors such as visual condition and cleanliness, all fall on some sort of priority list determined by the buyer. Depending on the buyer's priorities, a car with 72,000 miles on it may not even be considered, even if it is the right brand, type, and is in good visual condition. This buyer sees low mileage as a must-have trait, even if a car checks all of the other boxes, mileage trumps all of them in this case.
The hardest part about buying a used car is figuring out your priorities. A major drawback about buying used is that you have no say in customization, or trim package the car has, you get what you can find. To make the right choice, you have to make a clear list of priorities or you will be overwhelmed by a ton of numbers and end up with too many, or two few options. The whole process is a complicated and tedious balance of substitutions and compromises that can easily be daunting if you don't know what your priorities are.
