1971 Jaguar E-Type Series III Roadster


1971 Jaguar E-Type Series III Roadster

In 1971, the Jaguar E-Type Series III introduced the V12 engine to the model. This raised the car’s appeal on paper by having much more exotic specification. Jaguar called it the “Ultimate Cat” and advertised the car’s inherent smoothness and absence of engine noise.

Both the Coupe and Roadster were built on the longer 2+2 chassis which meant the Borg Warner automatic transmission was available on all V12 xkes.

Weighing in at 680 lbs (300 kgs) the small block V12 displaced 5.3 liters and produced 314 horsepower. It was an all-new sohc V12 utilizing four Stromberg carburetors.

Much of the E-Type structure had to change to accommodate the new V12 including widening of the engine subframes and a wider track. This included using the Saloon rear subframe assembly which added 3.25 inches of track.

Visually the car had a new eggcrate grill, wheel arch flares, four exhaust tips. Mechanical upgrades included larger brake discs and a larger fuel tank.

Inside the V12 had an entirely new interior with new reclining seats, a plastic center console, new door panels and a revised steering wheel. The dashboard retained much of the Series II layout, but included the 2+2 stowage areas above the floorwells.

Production of the Series III roadster reached 7,992 cars.

1971 Jaguar E-Type Series III Roadster

1974 Jaguar E-Type Series III V-12 Convertible – sold for $82,500 This final-year Jaguar E-Type Series III Convertible is likely one of the best original examples today. With just one registered owner, a Michigan doctor, and a mere 6,300 original miles from new, it is striking in “triple black” and well-equipped with factory air conditioning, a four-speed gearbox, chrome wire wheels, and a tasteful conversion to European-specification bumpers. Displayed in a Jaguar dealer showroom since 1995, it remains absolutely original, with the exception of a single exterior refinish completed by Largo, Florida’s Predator Performance as part of a comprehensive, concours-level freshening. Now offered in superior condition and fully equipped, this superlative example is proudly offered for the enjoyment of another caretaker.

1974 Jaguar E-Type Series III Convertible
– sold for $63,250
Today, this is certainly one of the finest original Jaguars in existence. This time-warp example wears all original paint except for one very small “touch-up” on the driver’s side rocker panel. Unlike many survivors, the original paint here shines nicely, and the chrome and stainless trim are even better. The interior surfaces are also original factory pieces without any dye work or originality “enhancements” except for some fresh stuffing inside the driver’s seat headrest. The convertible top is the only one the car has ever worn, and it shows some age but is presentable and will do the job. It goes without saying that engine, transmission and body numbers all match the data plate and that all factory stickers and VIN tags are in place. We are delighted to present such a remarkable Jaguar and encourage very close inspection from enthusiasts.

– sold for €44,850
This desirable, manual-transmission Series III roadster was purchased by the immediately preceding owner in 2004, having already been restored to the very highest standards. Indeed, it is understood that the E-Type won the Jaguar Car Club of North America’s National Championship in 2000. The car was purchased by the current vendor in August 2007, since when the unattractive US-specification bumpers have been replaced by the much more elegant European type. Finished in British Racing Green with tan leather interior and equipped with chromed wire wheels, this well restored late-model E-Type is described as in generally very good condition, having been serviced regularly, and is offered with Netherlands registration papers.

1972 Jaguar E-Type Series III V12 Roadster – sold for €59,800 This beautiful E-Type was imported into the Netherlands in the 1990s from sunny California by ‘The Roadster Group’, a company that specialised in sourcing low mileage cars from the USA. At the time the Jaguar had approximately 16,000 miles recorded on the odometer, and was sold to a Dutch gentleman who moved to Belgium in 2001. The last Dutch technical survey (dated 21/5/2001) shows a recorded mileage of 17,571, while at the first Belgian technical survey on 26th September that same year the mileage was recorded as 19,229 miles. Since then the car has seen very little use, making only a single ‘around the block’ trip of a couple of miles each year. The current mileage is only 19,474, which is approximately 31,360 kilometres!

This particular car is a rare E-Type from 1973 that is in extraordinarily original condition and, as such, could be shown with pride in any “survivor” or “preservation” class forum. Showing just 17,000 miles on the odometer, it is painted in classic British Racing Green along with green leather interior and black convertible top. It was delivered new in England and is an original car with its original interior and mostly original paintwork from the factory. The top boot is also the original unit, and the car wears its tires as delivered, including spare.
