In what year was the last Grumman LLV built?

The last Grumman LLV was built in 1994.

Grumman produced the Long Life Vehicle from 1986 through 1994 for the United States Postal Service. The first production vehicle was completed in April 1986, after Grumman and General Motors won the Postal Service’s competition to create a purpose-built delivery truck. More than 100,000 LLVs were ultimately purchased for postal operations.

The truck’s aluminum body was mounted on a General Motors chassis related to the Chevrolet S-10 Blazer. Its right-hand-drive layout placed the carrier beside the curb, while a metal tray occupied the passenger-side area for sorted letters. These features made the vehicle highly practical for residential delivery.

The 1994 date refers to the end of LLV production and the last vehicle purchased by the USPS. It is easy to confuse that date with later postal-vehicle developments: the USPS acquired Ford-Utilimaster FFVs in 2000 and 2001, and electric LLV conversions were tested during the 1990s and 2000s. Those later projects did not extend regular Grumman LLV production.
