Some drivers don't pay any attention to their vehicles until something breaks. Others take them into their service repair facility for maintenance even before a problem develops. Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time.
Your vehicle has gaskets in several places. They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails. Eventually, after time, you will have to get gaskets replaced.
Same goes for belts. Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner. Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point.
You'll also find yourself buying brake pads. As much as you may try to go easy on them, brake pads work by wearing off a little bit of them each time they help you stop your vehicle. Do a lot of stop-and-go driving and you'll hasten the process.
No battery lasts forever, and your vehicle's battery is no exception. It can only charge and discharge electricity so many times. Count on getting no more than 4 or 5 years out of a battery, fewer if you live in a very hot spot.
Other parts that don't age well? Tires. They can have plenty of tread left on them, but rubber gets old and loses its flexibility. Tires have their date of manufacturer stamped on them for a reason.
Finally, your muffler is being subject to moisture from inside and out: inside because of moisture-containing exhaust and outside from the elements outdoors. Stainless steel or other alloys will last longer, but after a while, either the moisture or constant pounding from vibrations will take their toll.
That's why it's important to maintain every part on your vehicle. You can't wave a magic wand and make everything last forever, but take care of your vehicle and it'll take care of you.
