A modern car is loaded with features, knobs, and buttons. You may not need them most of the time, but you should be confident that they will work if and when you do need them. Before you begin your test drive, try out all of the various tools and accessories in the vehicle, such as windshield wipers, seat adjustments, mirror adjustments, window controls, radio controls, and even the sound system. If everything works well, it is a good sign.
When you are out on a test drive, the sales associate who rides along may try to persuade you to do a quick drive around the block before heading back to the lot. However, this route most likely won't allow you to gain a complete understanding of the car's performance. The best way to do so is to test drive it on an unplanned route that includes both highway and city driving. This will allow you to get a better understanding of how the vehicle accelerates, how it slows down under braking, and the ease with which it turns in tight corners.
Smartphone connectivity has become one of the top features that potential car buyers look for. However, the ease with which you can connect your phone to the vehicle can vary quite a bit from one car to the next. Depending on the car you are in, you may be able to connect your smartphone with a simple touch, or you may have to navigate through menus and submenus to accomplish the task. Test the smartphone connectivity as a part of the test drive.
If you are upgrading your car, you may encounter a host of new features that weren't there in your previous vehicle, such as advanced cruise control, automatic emergency braking, or lane keeping assist. Take the time to understand them and test them out before you make your purchasing decision.
