It would be great if cars ran perfectly from the moment you bought them until the moment you sell them or trade them in. However, things don't always work this way, so you want to make sure you do your best to be prepared for as many potential issues as possible. Here are some auto parts and tools you may want to have on hand, as well as some other info:
A jack and lug wrench
In many cases, a car will come with a jack and lug wrench. However, there are some models that don't in an effort to cut down on weight. Make sure you have a jack and lug wrench in your car, as well as a spare tire. If you end up getting a flat tire, then you may prefer to quickly change it on your own and get on your way instead of waiting for a tow truck to come to do it for you. You should also go to the auto parts store to purchase a can of tire spray to fix a flat, which can help you get your car to the tire shop if you get a flat in a location where you wouldn't feel safe changing the tire. Also, have some road reflectors so you can keep yourself safer if you get a flat at night.
A battery charger
It's a good idea for you to have a battery charger. You may want to always have it in the car with you. However, they are great for a lot of reasons. If you have a battery that goes dead on any vehicle, including off-roading vehicles, because they haven't been started in a while, then you can conveniently charge the batteries.
Belts and hoses
Belts and hoses are some of the parts that tend to need replacing more frequently than other parts. Luckily, they don't tend to cost very much. If you travel quite a bit, then you may want to carry a toolbox with you that has basic tools in it, along with some new hoses and belts that fit your car. Depending on how confident you are when it comes to basic repairs, you may be able to replace a belt or hose yourself if the need arises. However, even if you don't feel up to it yourself, you may be able to get someone to help you if you end up in a predicament while you are out of town.
Windshield wipers, fuses, and lights
These are some other things you should consider keeping in the truck of your car. This can help to keep your car on the road when you need to replace one of these items when you can't get right to the auto parts store.
