By shopping in the classifieds, you can find a great car for a fraction of the price of what you might pay at a dealership. For budget cars like the Nissan Pathfinder, you might save a little. For luxury cars like the Nissan GT-R, you might a lot. You might even save thousands.

Unfortunately, many unethical sellers can list their cars in the classifieds alongside those amazing deals. To make sure you are really getting the best buy on a quality vehicle, you’ll need to know what to look for. Here are a few things you can do to make sure you are getting a great buy from the classifieds:

Maintenance Records

Maintenance records can tell you a lot about the condition of a car. If the car has been well cared for over the years, it will be of higher quality now. Owners who keep maintenance records are also more likely to take better care of their vehicles.

Whenever you look at a potential car to buy, make sure you ask for maintenance records. If you are lucky enough to find a car that comes with these records, you can feel confident that you’ve found a good buy.

Low Mileage

Cars wear down primarily with mileage, not necessarily with age. The lower the mileage on a car, the better its likely health.

When you are shopping for a car, it’s important to look not just at its total mileage, but also at its mileage compared to its age. Fifty-thousand miles might seem like low mileage — until you find out the car is only two years old. However, 50,000 miles is very low mileage if the car is 10 years old.

A Sound Interior and Exterior

Another great sign that the car has been well cared for is a nice-looking interior and exterior. Sure, these things don’t influence the way the car runs, but if they are in good shape, it’s a good indication that the owner has put as much care into protecting the engine as he has put into protecting the way the car looks.

The classifieds can help you find a great car at a great price. Make sure that whatever car you get is great quality by using these tips to evaluate it.
