* Make and model: Some cars hold their value better than others, so the make and model of the car you're looking at will have a big impact on the price.
* Age: The age of the car is also a factor, as older cars tend to be less expensive than newer cars.
* Condition: The condition of the car is also important, as cars with more wear and tear will be less expensive than cars in good condition.
* Market conditions: The current market conditions can also affect the price of a used car. For example, if there is a high demand for used cars, prices will be higher.
In general, you can expect to pay anywhere from $10,000 to $25,000 for a used car with 12,000 miles. However, it's important to do your research and compare prices before you buy a car, as you may be able to find a great deal if you're patient.
