    Suffolk Jaguar SS100

    Suffolk Sportscars is dedicated to the production of the visually exact reproduction of the legendary Jaguar SS100, we have been in continual production of these cars for over 20 years. It is a pure and true in it's form, and is fully recognised and accepted by all the Jaguar car clubs around the world.

    The SS Jaguar 100 was originally designed in 1935 by William Lyons, the founder of Jaguar Cars Limited. You will find a history of the SS Jaguar 100 within our new website.

    The SS Jaguar 100 is one of the most important cars every produced in England. It marked the high point of English sports car design before the start of World War II. When the leading motoring writers of Europe selected their choice of the 100 most important cars of the 20th century, they included the legendary SS Jaguar 100. Surely there cannot be a more iconic or widely recognised car ever produced in such limited numbers. Only 314 SS Jaguar 100s were ever made, so for a car to be so well recognised signifies it as one of the most significant Art Deco vehicle designs, and also, a hugely significant vehicle in British motoring history.

    We have now made over 315 of our Suffolk SS100 Jaguar reproductions and in 2017 we will have produced more cars than the 314 units produced by William Lyons and SS Cars Ltd. We hope that this website will give you the confidence in our products and that you may take the opportunity to come and visit us at Woodbridge. I can tell you that even after over 20 years of making the SS100 I still get a smile and goosebumps whenever I’m ready to go for a drive.

    At Suffolk Sportscars we combine all the superb visuality of the original SS100 with modern brakes, steering, power and safety to meet the demands of today’s drivers. This is a great car to go touring in so you can plan to drive hundreds of miles in a day and do so in great comfort. The Jaguar XJ6 is one of the most comfortable saloon cars ever built and the suspension set-up on our car uses all the components that made this level of comfort possible.

    Within this website you can learn more about making the dream of one of the most iconic sports cars an eminently usable and enjoyable reality, at a realistic cost. We build numerous cars every year to bespoke customer specifications, and never build for stock. We can build you a bespoke car that you can truly call your own, with your choice of colour and trim, mechanical specification, trim level and optional extras. You can see cars that we have previously built in the gallery section of our website.

    We can also provide a self build package, where the vehicle comes ready for simple assembly and fitting at home, with a full set of reconditioned and new parts - effectively providing a big boys Meccano set.

    Finally, we aim to carry stock of our approved preowned Suffolk cars, although this is not always possible. We pick and choose to resell only the finest examples, and all cars come fully prepared to the best standards, with works guarantees, and ready for sale. Many cars carry historic registration, so can be exported worldwide to a great number of countries.

    In fact, Suffolk cars can now be found in over 50 countries of the world.

    Suffolk SS100 Bespoke

    Suffolk 100 Jaguar

    The Suffolk SS100 Jaguar is the ideal combination of the authenticity of a 1930s Jaguar sports car, mixed with modern engineering and technology, to provide the most exhilarating driving experience.

    Under the completely accurate 1937 SS Jaguar 100 coachwork and visual appearance, lies something rather different and better than the 1930s equipment. A bespoke designed and meticulously-built MIG welded box section steel chassis, which carries full Jaguar running gear and mechanicals. With a 4.2 litre XK twin cam straight-6 engine, servo assisted disc brakes, rack and pinion steering and adjustable coilover suspension - it has a performance and handling that excels its appearance, and indeed many of it's competitors.

    When we build a Suffolk SS100, we always build the car to a bespoke customer specification, meaning that when you order a car, you can choose from an infinite number of paint and trim combinations, as well as a wide range of optional equipment and special order items, to create a car that is truly one of a kind.

    On the road the Suffolk has all the feel of a much more modern sports car, and with engine output between 200-300bhp, in a car weighing approximately 1250kg, it has the performance to match one too.

    The cars have proved to compete well in Hillclimbs and track days against many a more modern car, but are also supremely comfortable from within the passenger compartment, so that one can easily feel comfortable travelling a few hundred miles in a single day without discomfort.

    The car can be specified to order in LHD or RHD and can be ordered with manual or automatic transmissions. The engine can also be specified with different capacities and power outputs.

    Standard Equipment:

    • Standard or metallic paintwork colours
    • 18" 72 spoke silver wire wheels (colours optional)
    • Black mohair hood, side screens, tonneau cover and hood bag (colours optional)
    • Folding windscreen with aeroscreens
    • Handmade leather trim and Wilton carpeting in choice of colour
    • Trimmed lockable compartment with toolkit, wheel hammer and jack
    • Moto-Lita wood rim steering wheel in 16" or 15"
    • Luggage rack in stainless steel
    • 4235cc Jaguar XK engine - remanufactured to as new condition
    • 4-speed all synchromesh gearbox with overdrive (5 speed or automatic optional)
    • Electronic ignition
    • Stainless steel exhaust system

    We are pleased to be able to build a Suffolk SS100 Jaguar reproduction to a customer order and offer a 12 month guarantee against the specific failure of any mechanical part. We undertake to supply replacement parts on an exchange basis only.  Cars requiring labour as part of their 12 month guarantee can be returned to our works at the customer's cost, so that the repair can be carried out for free.

    We also offer a 10 year guarantee against corrosion of the chassis or bodywork (UK only).

    Completed cars are supplied with the latest British Department of Transport Vehicle Registration Document V5C and a 12 month MOT certificate.

    We can also register our cars as new 2017 vehicles via and SVA test and then transferrable cherished registrations can be applied to the cars for UK use.

    Each Suffolk SS100 Jaguar is constructed using the original vehicle identity complete with fully rebuilt mechanical parts from a Jaguar XJ6 4.2 Series II or III. However, we can also use 1964-1968 Jaguar S Type identity and mechanical parts that can simplify registration regulations in certain countries.

    We have exported completed cars to most European countries and also to the USA, Canada, South Africa, Australia and New Zealand.

    Catalytic converters are not necessary but can be fitted where local regulations require.
