Porsches and homologation specials up for sale at next Silverstone Classic auction

The first day of the Silverstone Auction September sale is dedicated to Porsches, but the second day has plenty of desirables, too

On September 28, Silverstone Auctions will be hosting its annual Porsche sale where a range of rare and sought-after 911s and 356s are set to go under the hammer. But if Porsches aren’t your thing, don’t worry, as the day after sees another auction full of both classic and more modern machinery.

A star lot is one-of-six right-hand drive Porsche 356 C Carrera 2 2000 GS that’s up for sale. Its rarity and large guide price of £550,000 to £650,000 are definitely noteworthy. But there are other, cheaper, more common Porsches in the first day of the auction that look even more exciting.

If it’s older Porsches that do interest you, the rally-prepped 1958 356 A in the sale looks like the perfect driver’s classic. Featuring a set of tiny bucket seats, all the timing gear you need for a regulatory rally, some suspension modifications and a hot 1720cc engine, it’s ready to be enjoyed on an endurance event or just on a twisty B-road. It’s considerably cheaper than the aforementioned GS too, with a guide price of £65,000 to £70,000.

It might be considerably newer and undoubtedly faster, but the 2018 Porsche 911 GT3 Touring in the sale has a similar attitude to the outlaw 356 A – a smooth subtle body over a car designed for fast road driving. This Touring has only covered 400 miles so still hasn’t been properly run-in and is almost brand new. That usually hints at a massive premium over a new car, but the estimated price for this car is £150,000 to £175,000 – still over £30,000 more than the car was new, but not the obscene prices people have asked for GT3s in the past.

Some of the most extreme Porsches in the sale aren’t, in fact, Porsches at all, they’re Rufs. Ther two cars are a 993-based BTR2 – with a 420bhp single turbo air-cooled flat-six – and a 996-based RTurbo. This second car was used by Ruf in its promotional film staged at the Nürburgring in the early 2000s. In an homage to its famous Faszination on the Nürburgring film, where Stefan Roser expertly piloted a Ruf CTR Yellowbird around the 12.94-mile Nordschleife circuit, the newer film featured this yellow RTurbo in similarly spectacular fashion. The RTurbo is expected to sell for between £180,000 and £220,000 while the BTR2 expects to fetch £150,000 to £200,000.

There’s also plenty of other models on offer, such as a 914, 924 S and Turbo, a Panamera Sport Turismo and two of Porsche’s finest transaxle cars, the 968 Club Sport. Both the cars in the sale are black with silver wheels, complemented with the usual Club Sport script running down the side. The first example has only covered 40,000 miles and has a guide price of £36,000 to 42,000, the second car 61,000, so that’s expected to sell for a little less, £30,000 to £35,000.

The highlights of the second day’s auction are a vast range of rally and race homologation specials. From Ford there’s two Cosworth-powered cars, a Escort RS1600 with an estimate of £60,000 to £70,000 and a Sierra RS Cosworth that’s been upgraded to RS500 spec for £37,000 to £42,000.

The Sierra’s on-track competition, the BMW E30 M3, is also in the sale. There’s a 2.3-litre M3 Evolution II expected to sell for £60,000 to £70,000 and a rare 2.5-litre Sport Evolution model that’s a bit more expensive at £75,000 to £90,000.

There’s also an Audi Quattro with a guide price of £50,000 to £60,000, a 1984 Renault 5 Turbo 2 (£70,000 to £80,000) and a 1992 Lancia Delta Integrale Evo (£35,000 to £40,000). If you do have the self-control to resist bidding on the first day and spending all your money on Porsches, you’ll be spoilt for choice on the second.
