If you spend a lot of time in your car due to your job, you want to be sure that you're comfortable. When it's time to go shopping at a used car dealership, you should keep your career in mind — if you're behind the wheel for several hours a day, ensuring that you buy the right used car is just as important as buying the right chair and desk if you're setting up a home office. While you should sit in the driver's seat of each car you're considering to evaluate how it feels, you should also make a point of looking for other features that will make every hour you spend on the road more enjoyable and safer. Here are some things to look for.

Cruise Control

Don't take for granted that every car you think about buying has cruise control. While many modern-day cars offer this feature, not all of them have it. For example, some base model vehicles don't have cruise control. This is a valuable feature for people who drive for long stretches, especially if you spend much of your day driving on the highway. With cruise control, you'll be able to set your vehicle's speed to the desired level and move your legs around a little, which you'll appreciate if you're driving for a couple hours at a time.

Bluetooth Sync

People who drive a lot for work will often spend much of their day on the phone. For example, if you work in sales, you might often be talking to customers and co-workers as you travel. Given that holding a cellphone can be dangerous and is illegal in many states, it's ideal to have a car with Bluetooth capabilities. This feature automatically syncs your cellphone to the car when you climb in, and you'll be able to carry on conversations without touching your phone.

Lane Departure Warning

Although you should always pull over if you're getting tired, you might occasionally find yourself driving when you're fatigued. If this is the case, a car with a lane departure warning will help to keep you safe. This type of vehicle has sensors that will alert you when your vehicle begins to drift to either side. If you're starting to doze off, for example, you'll hear the sound and be able to react quickly and keep your car under control in your proper lane. Then, you'll hopefully be able to take a short break so that you feel more rested for the remainder of the trip.
