Park a Carrera GT at a car show and you’re guaranteed to draw a crowd, but park one next to a 928 Club Sport and you’re going to present hardcore Porsche fans with a real dilemma. Some won’t know which to check out first, because Porsche built 1,270 of the V10-powered supercars meaning there’s a chance many Porsche enthusiasts have seen one at another event. But there’s almost zero chance they’ll have come across a 928 CS.
Many might not even be aware that Porsche built a 928 Club Sport. Only 19 production versions were constructed in the late 1980s, making it far less commonplace than the more famous 911 and 928 Club Sports, though the ethos behind the 928’s M367 package was no different and focused on stripping away luxuries to reduce weight.

Unlike most regular 928 S4s of the period, this Forest Green Metallic Club Sport has no sunroof, manual sports seats, and a five-speed manual transmission with a dog-leg shift layout. It also claimed to have a lighter exhaust, lighter magnesium-alloy wheels, and no underseal on the floor, which must make the 928’s already bad tire roar even worse at freeway speeds.
But the CS option wasn’t about freeways, it was about making a big, heavy GT handle even better on fun roads, so in addition to cutting around 220 lbs (100 kg) from the stock 928’s circa 348 lb (1,580 kg) curb weight, the M367 kit also included a 20 mm (0.8 inches) suspension drop, 15 mm (0.6 inches) of extra track width and a limited-slip differential.
The car seen here, which was initially retained by the Porsche factory, and is being auctioned by Broad Arrow in April, also has “SP” stamped on its 5.0-liter V8, which is rumored to indicate a different ECU and cams fitted than the ordinary 316 hp (320 PS) versions of the 5.0-liter V8 found in most 928s.
This car has racked up 76,300 miles (123,000 km) yet looks good enough to display in a museum. Hopefully, that won’t be its fate, despite its rarity and value. Broad Arrow says the car has had €65,000 ($70,000) spent on it over the last five years and expects it to sell for between $275,000 and $375,000.
