I like things that are ZERO maintenance as long as they last as long or longer than things that require maintenance. My parents bought a new Sears Coldspot refrigerator in 1939. Every 2 months, my dad would oil the motor. Even so, the motor burned out 10 years later and we took the motor to a shop to be rewound. My present refrigerator is 16 years old–the unit is sealed and it has required ZERO maintenance. In spite of my love for old automobiles, today’s cars require a lot less maintenance and do last much longer.
