One of eight prototypes, the current owner worked at the dealership that originally sold it.
Back in 1981, Porsche up-fitter, Carelli, built just eight of these C928 Convertibles as a feasibility study for a production drop-top version of the beautiful Porsche 928. The current owner worked at the showroom that originally sold the car to its first driver, who paid $103,000 for it in 1981. It was bought back from the dealership by the owner's father in the early 2000s. The car was produced in close cooperation between Carelli and Porsche, using top-notch company-approved materials.
With the top down, the roof is fully hidden in factory-fitted fashion. The Porsche is powered by a stock 4.5-liter V8, mated to an automatic transmission that sends power to the rear wheels. It has also been given an aftermarket muffler and exhaust tip. The seller claims there are 6,333 miles clocked on this rare prototype model. Perhaps unsurprisingly, despite the car's special story and rare status, the top bid at this moment is just $25,100, with the reserve not met. Check out the eBay ad for more details.
