In total, Porsche would produce 91 962s between 1984 and 1991. 16 were officially used by the factory team, while 75 were sold to customers. Some 956s were rebuilt as 962s, with two being previously written off and four others simply rebuilt. Three 962s that were badly damaged were also rebuilt and had been given a new chassis number due to the extensive reconstruction. Due to the high demand for 962 parts, some aluminium chassis were built by Fabcar in the United States before being shipped to Germany for completion. Derek Bell, a 5-time Le Mans winner, drove the 962 to 21 victories between 1985 and 1987, remarked that it was "a fabulous car, but considering how thorough (Norbert) Singer (the designer of the 962 and head of Porsche's motorsport division at the time) and the team were, it was really quite easy to drive."
