Starting in first gear
Good morning. A DeLorean that sold for $72,000 in April is back for a second lap, and as of last night someone had bid it to $70,088. We're choosing to believe the 88 was on purpose. With the car on the block and the company that built it 44 years gone as of this week, today is a DeLorean issue from top to bottom.
In today's newsletter, we'll get into:
Auction Desk: the same 8k-mile five-speed, six months later.
One Big Story: how Britain paid for a car factory in Belfast and what it got back.
Engineer's Corner: the two springs that make a 44-year-old gullwing door open itself.
Garage Economics: why the DeLorean business that works is the parts business.
Let’s roll.
THE AUCTION DESK
Same DeLorean, six months later, and the bidding is back near $70K
This 1982 DeLorean DMC-12 spent about 20 years with one owner before selling on Bring a Trailer in April for $72,000. It's back on the site now, offered on dealer consignment out of Wichita, Kansas, and bid to $70,088. It closes this afternoon at 3:39 PM ET.
The spec is the one DeLorean buyers look for. It shows 8k miles and has the five-speed manual transaxle behind the rear-mounted 2.85-liter PRV V6, rated at 130 hp from the factory. Gray leather, the original-style turbine wheels in staggered 14- and 15-inch sizes, air conditioning, power windows, service records, and a clean Carfax going back to 1997. The Kansas title carries an "Antique" brand. Kansas uses antique registration for vehicles 35 years and older, so this reads as an age marker rather than damage history, but it's a reasonable question for the seller.
The more interesting part is the round trip. At a 5% buyer's fee, April's winning bidder paid about $75,600 all-in. For whoever owns the car now to get back to even, the hammer needs to land somewhere around $76,000, before counting transport, any work done since spring, and the dealer's share. The car hasn't changed much in six months. What this auction tests is whether April's $72,000 was the market or one strong afternoon.
My call: I think it clears the current bid without much trouble. Low miles plus a five-speed is the combination that draws DeLorean bidders, and the April result gives everyone a number to anchor on. I have bidding ending between $74,000 and $79,000. Whether that's enough depends on a reserve set by someone who paid about $75,600 for the car in the spring.
📈 Market signal: Dealer retail asks for driver-grade DMC-12s run roughly $56,000 to $66,000. Cars under 5,000 miles are listed from about $110,000 to $150,000. At 8k miles, this car sits between the two bands, nearer the bottom on price and nearer the top on condition.
ONE BIG STORY
Britain spent £77 million to build a car in Belfast. It got about a quarter of it back.

Forty-four years ago this month, the company behind the DMC-12 fell apart within eight days. John DeLorean was arrested at a Los Angeles hotel on October 19, 1982, and the company was declared bankrupt on October 26. The car is remembered for a movie. The factory behind it is a story about public money.
In 1978, DeLorean was close to a deal to build his car in Puerto Rico. Northern Ireland's Industrial Development Board made a late counteroffer, and he took it. The British government wanted jobs in West Belfast during some of the worst years of the Troubles, and DeLorean promised about 2,500 of them. Construction started at Dunmurry, on Belfast's western edge, in October 1978. Sixteen months later a 660,000-square-foot plant was standing.
The car was due in 1979. It arrived in early 1981, after Lotus re-engineered most of the original design. The "12" in DMC-12 came from a $12,000 target price; the launch sticker was $25,000, about $89,000 in today's money, and it landed in the middle of an American recession. By late 1981 the company had sold roughly 6,000 cars against a break-even point of 10,000 to 12,000 a year.
The rest moved quickly. In January 1982, a planned stock offering of about $27 million was cancelled after the SEC questioned the company's viability. The Belfast operation went into receivership in February. In October, an FBI sting recorded DeLorean discussing a $24 million cocaine deal he believed would rescue the company. A Los Angeles jury acquitted him in August 1984 on grounds of entrapment. By then there was nothing left to rescue.
Northern Ireland's auditors later added up the bill. Between July 1978 and February 1982, the government put about £77 million into the project, very roughly $150 million at the exchange rates of the day. Getting it back took 20 years, including a 12-year lawsuit against the company's auditor, Arthur Andersen. The state recovered £40.45 million and spent £20.72 million doing it, mostly on legal fees. Net recovery: about £19.7 million.
Spread across roughly 9,000 cars, the public contribution works out to about £8,600 per DMC-12, or something like $17,000 a car at the time, on a car that retailed for $25,000.
The takeaway: The DMC-12 was a jobs program that needed five-figure annual sales to survive, and it launched two years late, at twice its planned price, into a recession. The government recovered about a quarter of what it put in, after two decades of legal work. Roughly 6,500 of the cars are still on the road.
ENGINEER’S CORNER
How a DeLorean door opens by itself

A DeLorean's doors hinge along the center of the roof. With a door closed, most of its weight hangs out past the side of the car. The torque needed to hold it up peaks early in the swing, while the door's center of mass is farthest out from the hinge, and falls away as the door rises toward vertical. Whatever lifts the door has to push hardest at the start and ease off near the top. No single spring matches that curve well, so DeLorean used two.
The first is a torsion bar running along the hinge axis. One end locks into the hinge pin; the other is anchored to the body. DeLorean's 1981 patent describes the setup: with the door open, the anchor bracket is rotated about 20 degrees and bolted down, so the bar is already twisted at full open. Closing the door twists it further. The bar stores the most energy with the door shut and pushes hardest at the beginning of the opening stroke, where the load is highest.
The second is a nitrogen-charged gas strut, the same kind of part that holds up a hatchback. Near the closed position, the strut sits at a shallow angle, so most of its force pushes along the door instead of lifting it. As the door rises, the angle opens up and the strut's effective lever arm grows.
Together, they hand off. The torsion bar does most of the work in the first foot of travel and relaxes as it unwinds. The strut picks up the load as its geometry improves. Between them they carry the door through about 80 degrees, and a properly balanced door rises on its own once the latch releases.
Grumman Aerospace made the torsion bars, from stainless steel preset at cryogenic temperature. Presetting is a standard spring-making step: the bar is deliberately twisted past its yield point in the direction it will work. The surface takes a permanent set, and the residual stress left behind lets the finished bar carry more working twist without sagging over time. For a spring that has to hold up a heavy door for decades, sag is the failure that matters.
The payoff is packaging. A DMC-12 needs only about 11 inches of side clearance to open its doors, less than a conventional door needs.
As an engineer, what I like about this design is that neither part is asked to do something it's bad at. A torsion bar's torque drops as it unwinds, and a strut's leverage grows as the door rises. Pairing the two is cheaper and lighter than engineering one exotic spring to follow the whole load curve.
Two practical notes for owners. Struts are wear items, and a door that won't stay up is usually a strut problem before it's a torsion bar problem. And because the bar stays pre-twisted even with the door fully open, it holds stored energy at all times. Adjusting or removing one is not a casual driveway job.
The takeaway: The DMC-12's doors work because two inexpensive parts with opposite force characteristics are matched to the door's load curve: the torsion bar handles the heavy start, the strut handles the finish. The result is a gullwing that opens in about 11 inches of space.
GARAGE ECONOMICS
The DeLorean business that works is the parts business

About 9,000 DMC-12s were built, and estimates put around 6,500 still on the road. For a car whose manufacturer went under in 1982, that's a high survival rate, and the main reason is logistics.
After the bankruptcy, a liquidator, Consolidated International, bought the unsold cars and the leftover parts. The parts sat in an Ohio warehouse for about 15 years. In 1997, Stephen Wynne, a Liverpool-born mechanic who had been servicing DeLoreans in Houston, bought the inventory along with the name and trademarks. Moving it to Texas took 65 tractor-trailers. His company, DeLorean Motor Company (Texas), has no corporate connection to John DeLorean's, and today runs a 40,000-square-foot parts and restoration operation in Humble, outside Houston.
Orphaned cars usually die one unobtainable part at a time, until restoring them stops making financial sense. The DeLorean avoided that because the original stock, and later the reproductions, sat with a single supplier. Owners can still buy what they need, which keeps cars in use and keeps the market liquid.
The prices reflect that. The DMC-12 stickered at $25,000 in 1981, about $89,000 in today's money. Driver-grade cars trade in the mid-$50,000s to mid-$60,000s, and this week's 8k-mile car sold for $72,000 in April. Most DeLoreans are still worth less than their inflation-adjusted sticker, and only the lowest-mileage examples clear it. For a 44-year-old car with 130 horsepower, values have been steady rather than speculative.
Building new ones has been harder. After Congress passed the Low Volume Motor Vehicle Manufacturers Act in 2015, the Texas company announced plans for 300 new DMC-12s at around $100,000 each. Federal rules weren't published until December 2019, and the project has been on indefinite hold since 2022. The electric Alpha5 concept, shown at Pebble Beach in August 2022 with a claimed 2024 launch, had not gone on sale as of this summer. Italdesign, the same firm that styled the original DMC-12, won an arbitration award of about $4.6 million in unpaid fees for its Alpha5 design work and went to federal court in Houston in January to enforce it.
This month the brand announced a team in Airspeeder, an electric flying-car racing series that opens its 2026–27 season in November. For year one, the team flies the series' standard Mk3C aircraft, and DeLorean supplies the paint and branding. No pilot or race date has been named.
The takeaway: Forty-four years after the factory closed, the dependable part of the DeLorean name is keeping roughly 6,500 existing cars running, and every effort to build new ones has stalled before a first delivery. If you own a DMC-12, the parts supply is the main reason it holds its value.
🏁 THE COOL-DOWN LAP
