Yes, but how would a surviving DeLorean car company change the auto industry?
As much as De Tomaso did with their Pantera.
For the non-car Nerds, that's 'Not very Much'
It's hard to have a working DMC and John Delorean running it at the same time.
Built in the wrong country with the wrong components with the wrong guy as Chairman
Doing some handwaving.
1st PoD John D gets bumped on the head after his 1st marriage, and isn't so much a playboy as OTL. He still is one, just a little more straight dealing with people. It's a low bar.
1975, when he was first thinking of doing the mid-engined, wankel powered sportcar that eventually became the DMC-12,
gets the old Ford Assembly Plant in Dallas for cheap.
Good transportation links, and infrastructure. There's still people around who had worked there, when it was shuttered in 1970.
Get some tax financing/State aid to restart production, and open as a non-Union Plant to get the local Pols to opt-in
Unlike the Irish Government OTL, Texans are used to dealing with connivers like John, so he would have to produce a business plan that's founded in reality.
For motors, he gets a deal for the Buick 350 V8, a bit smaller and lighter than the Chevy V8, and use the Olds Toronado TH425 transaxle.
That gives good power and reliability for the 1979 model year, and not horrible gas mileage
