Gruppe P, Part X from The Bond Group and Road Scholars

The Bond Group and Road Scholars are back together to bring us Round 10 of their impressive, ongoing Gruppe P Collection. This time around, the headlining act is a Grand Prix White Porsche 959 Sport—the first of the 29 track-oriented Sport variants that were produced to be auctioned on Bring a Trailer. At the other end of the spectrum is an example of Porsche’s slowest vehicle—a rare narrow-track Junior 108S vineyard tractor. Four Slate Grey cars form a subset of the collection, each with extensive history and desirable specs, and other highlights include a 1600 Super Speedster, a 356B Emory Outlaw, and a low-mileage 993 C2S in silver over black. That’s a broad overview—the specifics are much more interesting, so let’s get into them!

Auctions for Gruppe P, Part X will begin going live on Monday, May 18. A preview of the collection continues below.

1988 Porsche 959 Sport

Decades after the release of the 959, it retains a singular status among Porsche’s halo cars. An oft-quoted line from Car and Driver scribe Csaba Csere explains why: “The Porsche 959 can accomplish almost any automotive mission so well that to call it perfect is the mildest of overstatements.” Just under 300 were built in total; this car is one of 29 Sport versions, which made 508 horsepower and were lighter than the more common Komfort variants. Features included monochromatic cloth upholstery, four-point harnesses, and a leather-clad roll cage, which also eliminated the rear seat. This particular car was converted to 540-horsepower “Stage II” spec by Porsche while with its original owner, and yes, there will be a driving video.

1959 Porsche-Diesel Junior 108S Tractor

This slim fellow is one of around 400 narrow-gauge 108S vineyard tractors built with their wheels tucked in so as not to damage the weintrauben. The model was designed to trundle along the sides of Alsatian slopes, but this example was delivered new to Seattle, Washington, and was purchased from the family of the original owner by Porsche tractor expert Steve Young, who spent the next nine years refurbishing it.

Slate Grey 1956 Porsche 356A Speedster and Slate Grey 1963 Porsche 356B Coupe

The first of the Slate Grey pair is a 356A Speedster that has a long history with @fiminod of The Bond Group. Like many 356 Speedsters, this car was purchased new by an American serviceman stationed in Germany. Forty years later, it was acquired by fiminod, who drove it from Massachusetts to Monterey twice in 1998 and 2004. It currently runs a 1600 Super engine (the stock one is included in the sale), and has some desirable equipment like Rudge knock-off wheels, GT-style bumper trim, fog lights, an 80-liter fuel tank, a Willhoit sway bar, a matching hardtop, and a cabin heater. Since he sold it in 2010 this Speedster has landed back with fiminod twice more, so he can represent it with intimate knowledge of its history and inner workings.

The Speedster’s companion is a 356B Super 90 coupe, also in Slate Grey over red leather. This car was with its original owner for 43 years and currently remains with its second owner, who purchased it in 2015. A repaint was carried out in 2015, fuel system work in 2025, and an engine rebuild in 2026.

Modified Slate Grey 1967 Porsche 912 Coupe 5-Speed and Slate Grey 2023 Porsche 911 Sport Classic

This hot rod 912 received $170k of work in 2018, which included performance upgrades and modifications from Willhoit Engineering of Long Beach, California. The car was finished in Slate Grey from the factory, and the same color was reapplied during the 2018 refurbishment. The engine has been punched out to 2.1 liters and the five-speed transaxle has been rebuilt with stronger internals and a limited-slip differential. Chassis tuning includes Bilstein shocks, a 15mm front sway bar, and Turbo tie rods, along with a dual-circuit braking system with Brembo calipers up front.

The last Slate Grey car is a distant descendant of the first three—a 992.1 911 Sport Classic. This limited edition of 1,250 are rear-wheel-drive cars with the engine from the contemporary Turbo S and touches recalling the 911 2.7 RS of the 1970s, like a ducktail spoiler and lightweight glass. This car also features tartan plaid inserts on the seats and over $29k of Special Wishes factory commissioning.

1957 Porsche 356A 1600S Speedster and 2.4L Polo-Powered 1960 Porsche 356B Coupe Emory Outlaw

In these two 356s from Road Scholars, we have a factory hot rod and a modern reinterpretation by Rod Emory. The Speedster, as you will recall, was a stripped-down spec requested by Max Hoffman for his American buyers, though this example was sold new in Switzerland and spent its early decades in the Alpine state before coming to the US. The car had already accumulated a heavy shelf of concours awards by the time the current owner shipped it off to Clark and Carter Restorations in Essex, England, in 2010, and it came back even better.

Rod Emory had already been building his famous “Outlaw” cars for a couple of decades by the time he completed this Azure Blue T5 356B in 2009. The revisions here may look subtle but are in fact extensive, starting with a reinforced floor pan fabricated by Emory. The extra rigidity accommodates the power of the 2.4-liter Polo four, which comprises two-thirds of a 930 flat-six—complete with twin-spark ignition and four-valve heads. The overall appearance has been smoothed out with removal of the external hood latch and the addition of Raydot mirrors, while 16″ Chris Coddington wheels carry wide performance radials.

4,500-Mile 1998 Porsche 911 Carrera S Coupe 6-Speed

For those seeking a nouveau-classic Porsche, a 4,500-mile 993 C2S in Arctic Silver over black leather is a fastball right over the plate. Likewise, the spec on this car is just right: three pedals, 18″ hollow-spoke “Technology” wheels, cruise control, the Motor Sound Package, and a limited-slip differential. Paint protection film was applied last year to keep everything fresh.

22-Mile Viola Metallic 2024 Porsche 718 Spyder RS Weissach

At the behest of its customers, Porsche let the Boxster and Cayman inch closer to matching the performance of the 911 range over the course of three generations. With the fourth they finally let it happen, bequeathing the 718 with the 493-horsepower naturally aspirated 4.0-liter flat-six from the 991 GT3 RS to the Cayman GT4 and its open-top sibling, the 718 Spyder RS. Unfortunately, you don’t get to see the motor, but such is the Boxster way. This delivery-mileage Spyder is finished in paint-to-sample Viola Metallic over black leather with Race-Tex inserts, and features the Weissach Package, which added titanium tailpipes, a Gurney flap on the rear spoiler, and exposed carbon fiber exterior accents.
