Dumpster Driving: Inside the Treasures From the Los Angeles ‘Junkyard’ Car Collection

Classic car enthusiast Rudi Klein was, by all accounts, a unique character.

The German émigré lived in Los Angeles, where he opened a junkyard called Porche Foreign Auto Dismantling (with the automaker’s name misspelled to avoid litigation). Klein, who passed away in 2001, took in only high-end foreign cars, mostly Mercedes and Porsche, but also BMWs and every brand of supercar, including many very rare examples. The junkyard’s trophies included famous Grand Prix driver Rudolf Caracciola’s 1935 Mercedes 500 K Special Coupe, a rare 1955 Mercedes-Benz 300 SL “Gullwing” (one of 29 with alloy bodywork), and many more.

Most, but certainly not all, of the cars that Klein bought were crashed, burned, or otherwise derelict. A German crew managed to get into Klein’s closely guarded sanctuary, subsequently producing the unauthorised 2017 photo book Junkyard . Many other people were turned away from the gates, and Klein charged such high prices for salvaged parts that purchases were fraught. The doors remained closed after Klein’s sons, Ben and Jason, took over. But now, everything is coming into the light as RM Sotheby’s prepares to auction cars from the Klein collection on Oct. 26 in its current South Los Angeles location, including those two notable Mercedes-Benzes.

Andrew Olson, car specialist at RM Sotheby’s, said Klein’s premises have “an interesting and special atmosphere—if we moved the cars, some of that would be lost. There’s still a rack of Porsche 356s. We took them out to photograph them, but then they went back to where they were.” In Monterey last year, the auction house staged a horde of storm-damaged Ferraris as if they were still in a collapsing warehouse. Klein’s yard provides natural staging.

There’s a total of 180 cars in the sale, Olson says. Most of what was in the yard will be sold, minus some extensively burned cars and those with a current value that would not justify restoration.

The 500 K Mercedes coupe has bodywork by Sindelfingen. It is a one-of-one vehicle, still wearing its original body. The car was restored and caused a stir at the famed Pebble Beach car show in 1966 and then again in 1978. But it was parked under Klein’s ownership in 1980, fortunately under cover. “The condition is surprisingly good,” Olson says. “It’s very solid and should be a straightforward restoration.”

The alloy-bodied 1955 Mercedes 300 SL was the only one delivered in black, and had once been owned by Ferrari importer Luigi Chinetti. The auction house describes it as “a unique example of the most sought-after of all 300 SLs, virtually unseen for decades.” Complementing it is a 1957 300 SL Roadster that was painted Fire Engine Red from the factory, with a cream interior, and coveted Rudge wheels.

The 1967 Iso Grifo A3/L Spider is a prototype built by the Italian coachmaker Bertone, and is the only factory-built Grifo convertible. Klein acquired the car, with Chevrolet V8 power, reportedly from auto enthusiast and Hollywood producer Greg Garrison. According to Junkyard : “It was one of Rudi Klein’s all-time favourites, and he hoped one day to rebuild it and take part in a classic-car rally in Bavaria.”

OpenAI says it is scrapping the release of its next-generation AI model over safety concerns that researchers raised during internal testing, in one of the clearest signs so far that agent misbehavior could stymie the industry’s rapid progression.

The move follows a summer punctuated by reports of artificial-intelligence systems industrywide going rogue, and marks a rare case of a major AI developer ditching a new release because of safety concerns.

The company had planned to launch the model, known as GPT-6.1 Astra, in the coming days or weeks, aiming for an October debut. The model was more capable than the company’s previous models in completing challenging tasks from end-to-end without human assistance, as well as writing.

The company instead will focus on improving the safety of future models, which it expects to be even more capable.

Saachi Jain, OpenAI’s head of safety systems, said in an interview that GPT-6.1 Astra regressed in two areas. Compared with its predecessor, GPT-6 Astra, the model performed poorly on tests measuring alignment, or how well the model adheres to what humans would like it to do. Specifically, GPT-6.1 Astra showed higher levels of deception: It wasn’t always honest about telling users of the actions it did or didn’t take.

Another issue was what OpenAI calls “scope authorization,” meaning that GPT-6.1 Astra would push ahead on a task without asking the user for permission, and would at times reach for external tools and services even if it might be unsafe.

“For anything regarding safety and alignment, there’s a trade off,” Jain said. “You really do need to find what’s the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction.”

While GPT-6.1 Astra improved in areas such as “model laziness,” Jain said it didn’t quite meet OpenAI’s bar for safety and alignment, so the company decided not to launch the model publicly.

The announcement comes one day ahead of OpenAI’s annual developer conference in San Francisco. In the past, OpenAI has used the conference as an opportunity to launch new models and services that reduce costs for software developers—a segment the ChatGPT-maker competes with rival AI company Anthropic to win over.

In recent weeks, OpenAI and Anthropic have called on industry partners to slow down the development of cutting-edge AI models and invest in safety standards, noting they will temper the pace of their own internal AI progress.

OpenAI says it is working to investigate a range of agent security incidents that it has discovered in recent months, and address the safety issues underneath them. As part of the work, the company has implemented a new monitoring system to catch AI-agent misbehavior more quickly, and started requiring engineers to use stronger security guardrails for testing its AI systems.

Earlier this summer hundreds of OpenAI’s internal agents, which were tasked with completing a cybersecurity test, ended up hacking into the AI company Hugging Face. Since then, high-profile organizations such as the Australian government and United Nations discovered that OpenAI’s agents used similar, but less extensive, techniques to gain access to their websites.

Many of the publicly known agent-security incidents involved OpenAI’s internal AI models that were never slated for public release.

Last week, OpenAI said it paused training on its most capable AI models after an AI agent slipped through a gap in the company’s internet restrictions to query a public chatbot. The company said its new monitoring systems flagged the incident within 15 minutes, and training on these models remains paused.

GPT-6.1 Astra isn’t one of those models, but a different case, the company said.

“We want to make sure our model development is safe no matter whether that’s in the company, or when we ship it to users,” Jain said. “But when we ship it to users, we have an extremely high bar in terms of safety and alignment.”

While the company decided not to ship GPT-6.1 Astra, it hopes to use the same base model to do additional reinforcement learning runs, and create future generations of its GPT-6 models.

OpenAI plans to conduct several deep dives to identify the root cause of the problems identified in GPT-6.1 Astra, Jain said. The work includes ensuring that OpenAI’s reinforcement learning environments are rewarding the right type of behavior, Jain added, though she noted the company would investigate all stages of model development.

AI companies have begun to draw scrutiny from policymakers and public officials, who are paying attention to the rapid development of the technology. Later this week, a Senate subcommittee is holding a hearing with third party AI researchers titled, “Rogue AI: Securing the Homeland Against AI Agent Attacks.”

Florida Attorney General James Uthmeier, a Republican, sued OpenAI in June, claiming that the company and Chief Executive Sam Altman knowingly released an unsafe product and ignored warnings that it could harm users.

In a motion for temporary injunction filed Monday, Uthmeier sought to prevent OpenAI from developing new AI models without third-party approved safeguards, stop ChatGPT from soliciting user engagement and limit the company’s ability to advertise ChatGPT as safe.

Tech companies claim they “cannot stop barreling forward with their potentially civilization-ending endeavors unless they are forced to do so by the government,” Uthmeier said in the filing. “The Florida Attorney General is answering your cry for help.”

An OpenAI spokeswoman said that people want to know AI is being developed safely, “and that starts with what companies like ours do ourselves.”

“Governments have an important role to play in setting robust safety standards for AI, and we’re committed to working with Florida and other states on advancing pragmatic AI policies that apply to the entire AI industry—not just one company,” she said.
