Unit production was scheduled to begin in 1979, but engineering delays and budget overruns caused the assembly lines to start only in early 1981. Workers at the factory were generally inexperienced; many never had jobs before joining DMC. This may have contributed to the reported quality issues attributed to the early production vehicles and the subsequent establishment of Quality Assurance Centers (QAC) located at various delivery locations. QACs were set up in California, New Jersey and Michigan where some of the quality issues were to be addressed and resolved before delivery to dealerships. Some of the issues related to the fitting of body panels, higher-output alternators, and gullwing door adjustments.
