Rubber carpets for the interior
Fabric mats create a cozy atmosphere in the car interior, but they are much more difficult to care for than rubber ones. Moreover, considering that in winter the roads are covered with a slush of snow, mud and reagents, and all of this gets into the car on shoes, rubber mats are a more practical option.

When you buy original carpets, you get their fastenings included (if it is provided) and a guarantee that the carpets will take their place on the floor of the car, unlike universal ones, which will most likely have to be trimmed to fit them in place.
Rubber mat for luggage compartment
A very useful thing, especially if the carpet has a high edge. After all, in the luggage compartment, in addition to the cargo that is periodically transported, there are always some small items and canisters with liquids lying around.

If liquids are spilled, the carpet will protect the trunk upholstery, and since it is rubber, it is much easier to wash and dry. In addition, trunk mats usually have a non-slip coating, so that the load will not move from one side of the trunk to the other during acceleration, braking, and turns.
Parking radar
A very useful thing when parking, as it helps to estimate the distance to a neighboring car or obstacle. Also, which is no less important, the parking radar will help to notice an obstacle that is not visible in the rear-view mirrors and rear window, but a child may be hiding behind the car or a dog or other animal may be running by. With certain skills, it is not difficult to install a parking radar yourself.

Rear view camera
As a type of parking radar, you can use a rear view camera that transmits the image to a monitor in the car. The camera will help with parking, reversing and when unexpected obstacles arise, and gives a more detailed view of the situation behind the car. The cameras have high image clarity and allow transmission of images in the dark. However, installing a camera and monitor requires a more painstaking approach and is significantly more expensive than parking radar sensors.
Seat covers
On the one hand, it is a very useful thing, as it protects the seats from dirt and preserves their appearance, since the fabric does not fade in the sun. On the other hand, under the covers you can't see the condition of the interior anyway, and most importantly: for whom should it be protected? For the next owner? Driving without covers is much more comfortable and cozy, so it's better to be more careful and clean the interior in a timely manner ("Car care"), rather than spoil the look of the interior with covers.
In addition, most modern cars are equipped with side airbags, which are located in the sides of the seats. Using covers will result in improper operation of the airbags in the event of an accident or side impact and, as a result, possible injury to the driver and passengers.
Navigator
Navigation systems are becoming more and more a part of our lives, as they have an undeniable advantage over a regular map: they plot the route themselves, calculate the distance and travel time, and some, when plotting the route, take into account traffic jams that have formed at the moment, which allows them to be avoided in time, without losing extra time.
Some vehicles have navigation systems as an option, while others do not. But there are many companies on the market that produce car navigators that can simply be mounted on the windshield. But when installing, remember that the navigator should not block the view and should not distract from the process of driving. Therefore, when choosing the screen size, keep in mind that a large screen will either block your view or have to be placed in an inconvenient place and its use will distract you from driving. A screen that is too small requires more attention to see the map and, accordingly, also distracts from control.
Some navigators can be used as a wireless headset for your cell phone, allowing you to take calls and talk hands-free.
