‘His and hers’ Porsche 911s up for auctionYou know how it is: you wait an age for a sand-beige coloured Porsche 911 S to turn up and then a pair of near identical twins roll into view. The Porsche double act from 1967 represents the star attraction at the IWM Duxford Auction on 29 March 2017.

These cars are only 300 chassis numbers or so apart, so the chances are they ‘met’ in Stuttgart all those years ago. Since they left Germany in 1967 they have taken different journeys, and while one car has been restored, the other still wears its original paint and interior. Remarkable, given its 50-year vintage.

Porsche 911 S: £220,000 – £250,000‘His and hers’ Porsche 911s up for auction

Choosing your favourite will be tough, not least because the pre-auction estimates for the two 911s are rather similar. If patina and originality are your thing, this one is for you.

It was delivered new to a dealership in Pennsylvania and is said to be “absolutely unique in that it’s completely original and unrestored”. The interior is similarly untouched and unrestored, displaying a wonderful 50-year-old patina.

We understand the 911 S recently completed a 1,000-mile tour of the Alps without issue, as you’d expect from a well-maintained Porsche. We only hope the new owner does the right thing and retains the car’s originality. If you’re after something restored, its twin sister might appeal…

‘His and hers’ Porsche 911s up for auction

Although both cars made their way from Stuttgart to the USA, they trod a different path once on American soil. This 911 S was sold new via a dealer in Texas, a full three months earlier than the unrestored car.

Its second owner bought the car in 1979 and it remained part of a private collection until 2015. The present owner then sent it for a 1,500-hour restoration project, resulting in what H&H is calling a “better than new condition”.

This restoration has shaved £10,000 off the upper end of the pre-auction estimate. We wonder if a buyer will be tempted to drop the £500,000 required to keep the siblings together. Read on to discover what else has caught our eye at the forthcoming IWM Duxford Auction.

BMW 2002 Turbo: £65,000 – £75,000‘His and hers’ Porsche 911s up for auction

As Europe’s first turbocharged production car, the BMW 2002 Turbo is guaranteed a place in the big book of motoring. But this German performance hero is more than just a footnote in a weighty tome. The 2002 Turbo is a 70s icon, and it could be yours for £65,000.

If that seems like a lot to ask when you can order a brand new M2 for £44,000, let us remember that this thing could show many an illustrious sports car a clean pair of heels. Nothing screams intent quite like a set of riveted arches and a KKK turbocharger.

This is a rare car – only 1,672 were built – and this one was delivered new in Italy back in 1975. Later, it became a showroom model for a BMW dealer in Spain, which might help to explain why it has covered a mere 23,720 miles since new.

Lotus Esprit JPS: £30,000 – £40,000‘His and hers’ Porsche 911s up for auction

To many people, the Lotus Esprit World Championship Commemorative will be forever known as the ‘JPS’, a reference to the black and gold F1 cars of the era. It was the first limited edition Esprit ever built and was built to commemorate “the world-beating combination of Mario Andretti and the Lotus 79 Formula One car”.

Along with the obvious black and gold cosmetic upgrades, each car featured a commemorative plaque signed by Colin Chapman and number on the three-quarter top panel. The original owner also received a framed photo of the Lotus 79 signed by Chapman.

The ‘JPS’ offered at the Duxford sale is number 99 of 99 built for the UK and was subject to a mechanical overhaul in 2007. A little online research reveals that the car was up for sale in 2014, at which point it had the same 61,000 miles on the clock and was ‘living’ in Switzerland. Interesting car, and the last numbered status gives it added provenance.

Audi Quattro: £45,000 – £55,000‘His and hers’ Porsche 911s up for auction

The Gilder Group was one of the UK’s oldest VAG dealerships in the UK and had managed to assemble a collection of cool classics. When JCT600 bought the VAG dealerships, the chairman shifted the cars to his own private collection. Now, they’re up for sale, with the lots including this 1985 Audi Quattro.

We’ll forgive H&H for using the phrase “time-warp example” to describe this Audi, because it really does look factory-fresh. There’s a mere 8,200 miles on the clock, along with a letter of provenance relating to its time in the Gilder Group Collection.

According to the vendor, the Audi “has never even had a touch-up stick applied to it, or one of its wheels refurbished”. The original WR engine is present and correct, along with factory stickers and an MOT until May 2018.

Ferrari 250 GT Pininfarina Coupe: £600,000 – £800,000‘His and hers’ Porsche 911s up for auction

No need to adjust your set, because this really is a Ferrari 250 GT Pininfarina Coupe. It’s just that it has been rebodied to look like a 250 GT LWB California Spyder. You’d be looking at a pre-auction in the many millions if it was the real deal.

Ferrari 512 TR: £135,000 – £155,000‘His and hers’ Porsche 911s up for auction

Eight years after the launch of the original Testarossa, Ferrari unveiled the much updated 512 TR model. Power from the 12-cylinder engine was increased, while improved aerodynamics contributed to a higher top speed. This particular car was supplied new to former England and Rangers legend Mark Hateley.

Ferrari F512 M: £170,000 – £190,000‘His and hers’ Porsche 911s up for auction

The third evolution of the Testarossa signalled the end for the pop-up headlights and the introduction of circular rear lights. It was Ferrari’s last mid-engine flat-12-cylinder engine production car and 501 units were built before production ceased in 1996. This example was delivered new in the Netherlands and has 16,500 miles on the clock.

Ferrari 360 Spider F1: £68,000 – £75,000‘His and hers’ Porsche 911s up for auction

The 360 Spider F1 was unveiled at the 2000 Geneva Motor Show, with styling penned by Pininfarina. This particular car was delivered new in Colchester and was treated to a number of options, including split-rim wheels and red brake calipers.

Ferrari 308 GTS Quattrovalvole: £50,000 – £60,000‘His and hers’ Porsche 911s up for auction

Don’t be fooled by the M-reg number plate, this Ferrari 308 GTS QV was built and supplied new in 1984. The 1995 plate refers to its date of registration in Japan, although it was actually imported to the UK last winter. We’d be hunting down a B-reg number plate if we owned this Fezza.

Ferrari 330 GT Nembo Spyder: no reserve‘His and hers’ Porsche 911s up for auction

Proceeds from the auction of this car will be going to the East Anglia Air Ambulance, so we invite you to dig deep. It’s the work of Nembo, a company that rebodied sports and race cars, in this case a Ferrari 330 GT 2+2. Former owners include the founder of the Bluebird Caravan Company and the chairman of the Ferrari Owners’ Club. You can expect to spend £500,000 on this bespoke creation.

Ferrari 330 GT 2+2: £200,000 – £240,000‘His and hers’ Porsche 911s up for auction

This is clearly a series one Ferrari 330 GT 2+2, as highlighted by the little-loved quad headlights, influenced by American trends of the time. These were later dropped, but not before Enzo Ferrari had used a S1 model as his own personal transport in and around the Maranello factory. A total of 1,080 units were built before production came to an end in 1967.

Ferrari 360 Spider F1: £85,000 – £95,000‘His and hers’ Porsche 911s up for auction

None other than David Beckham owned this 2001 Ferrari 360 Spider F1 and the former footballer was often pictured out and about in ‘D7 DVB’. Today, re-registered, the car has covered 7,800 miles and has recently had a cambelt change in Leeds. We doubt Beckham would have been that keen on a visit to Leeds.

Ferrari 348 TS: £36,000 – £40,000‘His and hers’ Porsche 911s up for auction

The 348 TB and TS models had it all – pop-up headlights, Testarossa-style slatted side air intakes and a glorious, longitudinally-mounted V8 engine, to name but three highlights. It overshadowed just about everything at the 1989 Frankfurt Motor Show. Yes, even the Vauxhall Calibra.

Ferrari Mondial 8: £30,000 – £35,000‘His and hers’ Porsche 911s up for auction

If the opportunity to buy ‘his and her’ 911s doesn’t grab you, perhaps you might prefer something Italian. The Mondial 8 never recovered from a lukewarm reception at the 1980 Geneva Motor Show, but it represents one of the most affordable ways into Ferrari ownership. This is one of just 145 right-hand drive coupes and it has a mere 14,000 miles on the clock.

Ferrari Mondial 8: £15,000 – £17,000‘His and hers’ Porsche 911s up for auction

If the previous Mondial 8 is ‘good to go’, this 1982 example will require a little work. ‘RET 295X’ is offered from a deceased estate and was last run some three years ago. Yours for the price of a well-equipped Ford Fiesta. Remember, the H&H sale takes place this weekend at the Imperial War Museum, Duxford.
