He has had a stroke and it's been years since I saw him out and about.
DeLorean was a high-flyer who let his media-driven 'legend' go to his head. He convinced hImself that he was not subject to the laws of economics and practical business - he tried to introduce an 'exotic' sports car into a national market with no post-sales support infrastructure. Even if he had managed to sell all 8,000 cars - there was no way to maintain them across the US.
autoweek says he was living in a 2 bedroom apartment in Morristown NJ at the time of his death, having gone through bankruptcy, he was selling watches over the internet to earn money - and amazingly, was involved in a project to develop a new sports car.
Our opinions on him differ - the guy was a brilliant engineer - and was targetted in that drug sting because it was known he was desperate to raise money to keep his company going. GM didn't everything they could to try and stop him from succeeding.
