Street-parked supercars are inherently cool but what we have here is many magnitudes more special. This Porsche 959 is one of the rarest variations of its kind, an S Prototype version, worth seven figures, and it was street-parked in San Francisco, a city known for its incredibly high theft. Did we mention that the keys were in the front seat and the windows were open?

Any Porsche 959 is very special and very valuable with only 337 being made overall, including just 29 examples of the more hardcore 959 S. The final production version was the fastest street-legal production car in the world for a time and was one of the first to feature adjustable suspension and AWD.

Spotted by two eagle-eyed Reddit users, u/SRV87 and u/kabobinator, this Porsche 959 is even more special though because it’s an S prototype. To be specific, it’s an “F9,” a 959 Sport or S prototype of which only 3 are believed to have been produced, featuring unique features not found in any other 959.

That’s why it’s so shocking that two different Reddit users found the supercar with its windows down and the keys in the seat on a street in San Francisco. There are a great many theories about why the car was left in that state but none seem to be very good.

Commenters pointed out that some drivers do this with normal cars in San Francisco in the hopes that thieves won’t break their windows. Of course, that doesn’t explain why the keys are in the car. Perhaps the driver is confident that few willing to attempt to steal this car will know why there are three pedals in the footwell, much less what to do with them. The folks at TireMeetsRoad even suggested that the key inside might not be from the actual 959, so anyone attempting to drive away with it would need to hotwire it.

Another suggestion is that this is probably just a stunt orchestrated by an influencer, with cameras focused on the classic supercar to capture people’s reactions. If that’s the case, it appears to be a risky way to garner attention for such a rare Porsche.

This exact car was on sale last year with Girardo & Co where it appears to have sold. Then, earlier this year, it was on sale again. Hagerty actually featured it on a lengthy review feature that we’ve shared below. Whoever owns it now certainly has a strange way of showing off their status.
