Definitely avoid anything built this century. They use plastic gears that strip out if too much torque is required (kneading dough, etc) compared to the metal gears used in the original model.

It actually depends on which model you get, and the plastic one also has advantages (if it breaks, its a sub $10 part, if the metal gears go its basically junk). As far as i know, the lift bowl pro models have metal gears. (Also they started using nylon gears in the 70s, better off with 90s or newer as they reinforced with kevlar).

That’s not a bad thing at all. It makes sure that if you overload the mixer, it’s a small easy part to replace than an entire more. The older kitchenaids have a plastic fail gear too—I’ve replaced them.

Idk, I’d rather replace a plastic gear than a whole gearbox or motor
