The Best Jowett Jupiter Mk1 On Earth?
Ok, that's a bold question, but this is arguably the very best Jowett Jupiter in existence. The restoration on this car was impeccable and done by renowned shop Speedwell Engineering in southern California. They are famous for their restoration and racing work with names such as Austin Healey and MG.
As best as we can tell, E1 SAL 523 was built in January of 1952, imported into Pasadena, CA and has been in CA since. This ground up professionally restored Jupiter has won 1st in Class awards, as well as showed and placed, in various Concours de Elegance events in southern California. Events included the Los Angeles Concours, the Palos Verdes Concours, as well as the Muckenthaler. She has been repeatedly invited to return as she's such a crowd pleaser. She was also asked to participate in The British Invasion exhibit at the San Diego Automobile Museum.
If you are looking for rarity, something unique, a centerpiece of conversation, a piece of mechanical art and engineering, with successful racing heritage and pedigree, look no further. Only 900 or so Jupiters were made during their entire production run. These were hand built cars that required much expensive design and craftsmanship. In terms of design, if you are unfamiliar with Juptiers, this is from britishclassifieds:
Jowett through Lawrence Pomeroy of The Motor joined forces with ERA and they persuaded Professor Dr Ing Eberan-Eberhorst, formerly with Auto Union, to come to England. He joined ERA in Dunstable and, amongst other projected development and chassis work, designed and developed what became the Jupiter's tubular steel chassis. The suspension used soft torsion bars and anti-roll bars front and rear with independent suspension at the front. The engine was mounted very far forward ahead of the front axle line with the radiator low behind it over the gearbox. Adjustment of the anti-roll bars easily influenced oversteer and understeer to provide fine suspension tuning. On this torsionally stiff frame Reg Korner of Jowett put a steel framed aluminum drophead coupé body with a bench seat for three people. Eberan's chassis had been designed for a closed coupé and it proved to require strengthening. The anti-roll bars were abandoned. There was no external access to the boot (trunk) and the bonnet (hood) was rear hinged and opened complete with the wings. These cars were only for export, it was hoped coachbuilders would supply the local market.
An initial 75 chassis were supplied to external coachbuilders such as Stabilimenti Farina, Ghia Suisse, Abbott of Farnham and others in Britain. The high cost of these, mostly handsome, bodies for what was only a 1500 c.c. car obliged Jowett to build their own complete cars. The Jowett factory made 731 Mk1 and 94 Mk1a cars.
As you may know, or not, in 1950, 1951, and 1952 Jupiter's finished first in their class at Le Mans:
Motor Sport Success
The Jupiter achieved competition success with a record-breaking class win at the 1950 Le Mans 24 Hour race, a class 1-2 in the 1951 Monte Carlo International Rally, an outright win in the 1951 Lisbon International Rally, and a class 1-2 in a gruelling 4-hr sports car race on the public road circuit at Dundrod in Northern Ireland in September 1951. This was a resurrection of the famous Ulster Tourist Trophy Race of 1928-1936 previously run on the 13.7-mile (22.0 km) Ards circuit. Le Mans was again class-won in 1951 and 1952, and lesser events were taken in 1952 but by 1953 newer faster cars were proving a match for the Jupiter which was after all a well-appointed touring car first and foremost.
The aluminum body on this example and is finished to a standard that's arguably better than when it left the factory. Her green paintwork is the original color and is incredibly high quality. During the restoration they found the original green color and color matched it perfectly. The body and paint are flawless. Chrome and bright work shine as new. You will not find better looking paint work anywhere. It is first class.
The engine is a horizontally opposed 1,500 cc unit (boxer engine like Subaru or Porsche), and the driver utilizes a 4 speed column shift gearbox to run through the gears. This car has been upgraded with dual Weber carburetors (the Zenith carburetors that came with the car are included in the sale). She starts immediately at the press of a button. Throttle response is excellent. Her gearbox shifts smoothly through all gears. All the instruments function as they should. Steering and braking work as they should, and the ride is sporty yet compliant.
The interior and leather appear as clean and fresh as they would have from the factory. Leather and carpets are the original colors. The dash and steering wheel (note the marbling) are impeccably restored, with all gauges crisp and bright. The fabric top is as new, with a glass window in the rear, and the top bows are polished stainless steel and as new. Glass and rubber trim all around the car are excellent.
The engine bay and undercarriage are sharp and crisp. She does get driven to shows and on joy rides so it would only take a quick wipe down underneath and in the engine bay to enter her in another Concours.
This car never fails to generate astonishment, oooh's and ahhhh's, people absolutely love it. When driving it the other day to take some photos people continually pulled over and stopped, got out of their cars and asked questions, complimented it, and asked to take photos with it. Even the neighbor's dogs posed obediently, and you'll note them in a few photos. That type of thing will happen often, so be prepared to spread some joy when you take her out for a spin.
You might find a tired Jupiter and pay to restore it to this caliber and spend an enormous amount of time and money. Or, you could buy this one for much less and be immediately on the road. Don't miss this once in a lifetime opportunity. This is the first time this professionally restored car has been publically offered for sale.
