June 17, 2023, Update – Less than one week after posting the ad for their non-running Porsche 964 project car, the seller deleted it without posting a replacement.  That’s a sign they sold the car at or near their $29,000 asking price.  We confirmed the seller of this “Classifind” deleted their listing, so we’re now able to call this one “SOLD!” While this one got away, please reach out either by email or call us directly if you’d like to be informed when we come across something similar.

We never thought it would last this long, but prices for air-cooled Porsches, particularly 911 variants, continue to remain strong for eight years and counting. What started as a Hipster fad around 2014 continues unabated despite a pandemic and a subsequent poor economy. This trend applies to every generation of the 911, from early “Long Hood” versions to the Porsche’s air-cooled swan song, the 993 produced from 1994 to 1998.

The next-to-last air-cooled Porsche 911 generation was the 964, launched in 1989.  Remember, by the late 1980s, Porsche had planned to phase out the 911 in favor of the company’s 928 flagship.  Consequently, the 964 generation was never supposed to materialize.  Even when it did, the Porsche Purists still condemned it as too much of a modernization of their beloved tail-happy rear-engined sports car.  Time has a way of healing, and now, the 964 generation is particularly desired by the Outlaw and Back Dating crowds.  Call it the Singer effect, but it’s getting hard to find a 964 vintage Porsche in original condition that hasn’t been scooped up by an enthusiast interested in either making a Restomod (“Outlaw in Porsche Parlance) or modifying the front and rear ends with older 911 components in an effort to “Back Date” the car.

Understanding those dynamics, it’s easy to understand how the seller of this Guards Red 1990 Porsche 911 Carrera 4 Cabriolet for sale, first spotted in June 2023 on Craigslist in Camarillo, California, set their asking price. Almost thirty large for a 177K-mile project car that has not run in over a decade may set off some, but someone is about to get a great deal on a desirable Porsche.  Even after an expensive engine rebuild and repaint investment, there’s a good chance the buyer can recoup their investment.

Last offered for $29,000,, the analytics and search engine for the collector car market, confirms the ask is well below the five-year rolling average of this guide’s summary for the 964-generation of all Porsche 911 Carrera 4 variants produced between 1989 and 1993.  By clicking on the green dots in the graph below, you can navigate to each comparable car sold as a way to help you evaluate the price of the Carrera 4 Cabriolet featured here:

As a second data point, the  Collector Car Market Review Online Tool reveals the seller’s ask falls between this guide’s #4 “Fair” estimate of $27,000 and its #3 “Good” appraisal of $49,000.
