The lack of demand, cost overruns, and unfavorable exchange rates began to take their toll on DMC's cash flow in late 1981. The company had estimated its break-even point to be between 10,000 and 12,000 units, but sales were only around 6,000. In response to the income shortfall, a restructuring plan was devised where a new "DeLorean Motors Holding Company" would be formed, which in turn would have become corporate parent to DMC and each of its subsidiaries: DeLorean Motor Cars Limited (manufacturer), DeLorean Motor Cars of America (distributor in the U.S.) and DeLorean Research Partnership (a research and development company). In January 1982, due to United States Securities and Exchange Commission questions about the company's viability, the company was forced to cancel the stock issue for the holding company that DeLorean had hoped would raise about $27 million.
John DeLorean lobbied the British Government for aid, but was refused unless he was able to find a matching amount from other investors. What followed is a matter of debate between the British Government, the US Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), DeLorean, his investors, and the US court system. At some point in 1982, John DeLorean became the target of an FBI sting operation designed to arrest drug traffickers. He was arrested in October 1982 and charged with conspiring to smuggle $24 million worth of cocaine into the US. The key element of evidence for the prosecution was a videotape showing DeLorean discussing the drugs deal with undercover FBI agents Benedict (Ben) Tisa and West, although DeLorean's attorney Howard Weitzman successfully demonstrated to the court that he was coerced into participation in the deal by the agents who initially approached him as legitimate investors. He was acquitted of all charges, but his reputation was forever tarnished. After his trial and subsequent acquittal, DeLorean quipped, "Would you buy a used car from me?"
In the end, sufficient funds could not be raised to keep the company alive. DMC went bankrupt in 1982, taking with it 2,500 jobs and over $100 million in investments. The British Government attempted to revive some usable remnants of the manufacturing facility without success, and the Dunmurry factory was closed. DeLorean himself retired in New Jersey, and the dream with which he had mesmerized Britain's Labour government, of industry rising out of the ashes of The Troubles in Northern Ireland.
