As the 1955 models went into production, an old problem flared up. Back in 1941, Packard had outsourced its bodies to Briggs Manufacturing Company. Briggs founder Walter Briggs had died in early 1952 and his family decided to sell the company off to pay for estate taxes. Chrysler promptly purchased Briggs and notified Packard that they would cease supplying bodies after Packard's contract with Briggs expired at the end of 1953. Packard was forced to move body production to an undersized plant on Connor Avenue in Detroit. The facility proved too small and caused endless tie-ups and quality problems. Bad quality control hurt the company's image and caused sales to plummet for 1956, though the problems had largely been resolved by that point. Additionally, a "brain drain" of talent away from Packard was underway, most notably John Z. DeLorean.
