You forgot to mention the exhaust system....Says those who are no were near 70 let alone 80. At about 55-60 like and old car, the tire are worn out the headlights are dim, the motor might still be strong, but the transmission is starting to slip, small but vital part start to break, fall off, need replacing. You might even need a battery tender permanently attached to keep the fluid pump pumping. Everything is old tired and creaks.
And it ain't going to get better!
