  However, Diplomats built from mid-1988 until the end of production were among the first Chrysler-built products to have a driver's side airbag as standard equipment, some two model years before the remainder of Chrysler's lineup and they were also among the only cars at the time to offer a tilt steering column with an airbag.

  Discontinuation
  When the Diplomat and similar Plymouth Gran Fury were discontinued, it marked the last rear-wheel drive sedan sold by the corporation until the Dodge Magnum and Chrysler 300 were introduced in 2005.  The Diplomat's other rear-wheel drive sibling, the Chrysler Fifth Avenue, also ended production, but the nameplate was continued on a front-wheel drive chassis. In the Dodge lineup, the Monaco became the top-of-the-line sedan until the introduction of the LH platform.
