If you keep your car well maintained, there’s no reason it shouldn’t last 20 years or more.  Most of that maintenance will be routine preventative care, such as replenishing fluids and changing tires. Occasionally components such as brakes and alternators will need replacement. What you probably won’t need  to do is completely disassemble and reassemble it.

But planes are different. We’re used to seeing assembly line pictures of airplanes. What you probably don’t realize is that it is completely routine over the course of an modern airplane’s lifetime to be stripped all the way down, have major components replace, and be completely rebuilt.
