The UPS package car (or van) is a major symbol of the U.S. business world, with its iconic status referenced in an early-2000s ad campaign following UPS' sponsorship of Dale Jarrett in the NASCAR Sprint Cup Series: the ads were about how the company would prefer to race the truck over a stock car despite the futility of doing so, as "people love the truck".
The classic UPS package car is built on a General Motors or Ford chassis, has a manual transmission, manual steering, and no radio or air conditioning. The older ones are easily recognizable due to their round headlights and turn signals set onto a sculpted fiberglass hood. These are either Grumman Olson or Union City Body P-500, P-600, or P-800 step vans (a recent redesign changed the look, replacing the round turn signals with ovoid LED ones). The cars lack manufacturer's name or badges.
Newer package cars in North America have either a Freightliner Trucks or Navistar International chassis; automatic transmissions and power steering are slowly appearing in package cars. UPS also operates Mercedes-Benz Sprinter box vans (occasionally with Dodge badges) as well as Dodge Grand Caravan minivans.
