Notes

The Volkswagen Beetle/New Beetle: discontinuous in major markets, though the "legacy" Beetle continued production for sale in Mexico. Not a true discontiguious name because the original model was never officially sold as a "Beetle."
The Mercury Monterey was reincarnated as a minivan.
The Chrysler Town and Country was reincarnated as a station wagon in 1965, then as a minivan in 1990.
Nissan's Z-car was discontinued during the late 1990s, and resumed production with the 2003 350Z.
Chevrolet is the current champion of this list.
