Factors Considered by the Car Value Calculator

A car’s value depends on many important factors, and the car value calculator looks at all of them to give a fair valuation. Some of the most important factors include mileage, ownership history, accident history, and the car’s current condition. Extra features like aftermarket accessories, the car’s color, and complete maintenance records can also change the price. The year, make, and model matter too because some cars are more popular or in higher demand.
