Are you considering buying a used car? If so, then there's a good chance your head is spinning thinking about all of the options at your fingertips. There is good news, however: All you have to do is take a deep breath and focus on a few key areas when you're browsing. 

The next time you shop around for used cars, keep an eye out for these five qualities that may impact your decision. 

1. Mileage 
Mileage is one of the first things people look at in a potential ride, and with good reason. It provides insight into the wear and tear a vehicle has gone through, while also outlining expected longevity and maintenance. 

2. Driving performance
How a car drives is also an important aspect you must consider. If the vehicle doesn't drive in a way you like, then it's probably not a good investment. In addition to taking a test drive of the individual vehicle you're looking at, research a few reviews of the model from professionals and owners. That will give you an idea of any recurring issues. 

3. Safety features
You don't realize how important a car's safety features are until you need them. That's why it's essential to scope out the features present in a used car. Crash test ratings can provide a look at how it'll perform in an emergency, but you should also check out any crash-prevention features to make sure they're still functioning. 

4. Low operating costs
The sticker price on a used car probably gets most of your attention, but if you're under a tight budget, there are more expenses you need to consider. Take a look at the cost to fill the gas tank, complete routine maintenance tasks and acquire replacement parts.  

5. Outside appearance
You can't judge a book by its cover, and the same can be said of used cars. However, that doesn't mean you should ignore the exterior of a vehicle entirely. Look for rust spots, which may indicate decay, or random dents and scratches. These should match up with any incidents on the vehicle history report so you know they've been cared for.
