Question: Where was the  Citroën vehicle designed with influences from what is called a beach buggy in the United Kingdom presented?

full_context: Document 1: Banger racing: Banger racing is a tarmac or dirt track racing type of motorsport event popular in the United Kingdom, Ireland, Belgium and the Netherlands, and to a lesser extent elsewhere in Europe. Old scrap vehicles are raced against one another, with the winner being the first to the chequered flag after a set number of laps. The race tracks are usually oval, around 440 yards (400 metres) but on occasion are constructed in a figure eight design.
Document 2: Paddle tire: Paddle tires are mainly used on off road vehicles, specifically designed for use in sand and mud. They consist of a smooth tire core which has a series of large rubber cups (or paddles) attached to it. The volume inside of a paddle is much larger than the void of a knobby tire, so it is unlikely to clog up with sand/mud. A street legal mud tire is a more or less normal tire, but with extra large gaps or "voids" between each tread block (called "lugs") to allow centrifugal force to "self-clean" or fling the mud out of the gap. Smaller gaps trap the mud in between the tire lugs, which turns the tire into something resembling a "slick" with no tread at all, which will have no traction in mud. A paddle tire is an even more extreme version of this, optimized for mud or sand. The paddle provides superior traction in the sand, in part, because the paddles dig into the sand and push off from the buried sand, not just the surface, and in mud, the gigantic "voids" give no place for mud to stick. They work something like a paddle wheel on a paddle-steamer. Street legal mud tires are a compromise between large voids and a smooth rolling shape for on-road use. The more "extreme" a mud tire (such as a "Super Swamper") is, the harsher and louder it is on a hard surface. A "tractor tire" on a farm tractor is a somewhat more mild version of a paddle tire, only the voids are smaller to allow for limited use on hard surfaces, and the "lugs" are angled to give lateral traction. A paddle tire is so optimized for mud that the shape is of no use on anything other than a soft surface, since the vibration and lack of control of the tire would render a vehicle almost unusable. One other way the paddle tire is a specialized-application-only is that it gives only forward/rearward traction. This means that it is used on a wheel that drives a vehicle to push it forward, but gives little "lateral" (side-to-side) traction. For that reason, the tires of the vehicle that steer it are generally more "normal" tires, since a paddle tire on a steering wheel will just slide sideways rather than pulling the vehicle with it. So many 4WD vehicles will use paddle tires only on the rear, although the front wheels are powered as well. On a 2WD or a motorbike, the rear wheel is the only drive wheel, and so putting a paddle tire on the front wheels is useless or worse, since steering performance will be negatively impacted.
Document 3: Michalak C7: The Michalak C7 is a kit car based on the Smart ForTwo. The C7 uses a stainless, fiber reinforced plastic body making it slightly faster than the Smart ForTwo because it is 170 kg lighter. Once the production version was released, Michalak sold some of the prototypes.
Document 4: Burton (car): The Burton is a Dutch sports car based on French 2CV technology. The Burton is an open, nostalgic-looking sports car built on the chassis of the 2CV with a modern glassfibre bodykit. The car can be built as an open two seater, or with a hardtop with gull-wing doors or with a custom made convertible roof. From the beginning of 2002 the Burton is available all over Europe.
Document 5: Concept Centaur GT: The Concept Centaur GT was a kit car first built by Concept Cars Ltd of Middleton, Leicestershire, in 1973 and marketed from 1974 to 1977. The design was very much influenced by the Probe 15 from Adams Probe Motor. The car is famous for possibly being the lowest car ever made being only 94 cm (37 in) high. It was based on the Hillman Imp mechanicals and the body was a GRP-and-plywood monocoque with box section and steel tube reinforcement. The number of models produced is disputed, both 26 and 52 cars have been quoted.
Document 6: Volvo Concept You: The Volvo Concept You is a concept car first revealed at the Frankfurt Motor Show in September 2011. The Concept You is an executive car with a 4-door fastback saloon-like styling and is a further development of the "Volvo Concept Universe" which was revealed earlier the same year. The design builds upon Scandinavian Design where simplicity, elegance and intuitively are key ingredients. Volvo has interpreted this to design the car around the driver and passengers in the car, hence the name "You". This includes, for example, that all buttons and knobs have been removed and replaced by easy-to-use touch-screen to control the features of the car. The exterior design is inspired by the classical Volvo models PV544 and the Amazon.
Document 7: Citroën Karin: The Citroën Karin was a concept car presented at the Paris Motor Show in 1980. It featured a striking, pyramidal design and was designed by Trevor Fiore. The exterior of the car incorporated flush glass panels, faired rear wheels, and butterfly doors. The roof of the Karin was only the size of an A3 sheet of paper due to its truncated pyramid shape. One of the Karin's most noticeable interior features was the unique three-seat layout with the driver located in the middle of the two passengers. Also among its features were a 4-cylinder engine, front wheel drive, and a hydropneumatic suspension like the Citroën DS.
Document 8: Off-road park: An Off-Road Vehicle Park is an area of land that may be accessed by all-terrain vehicles such as 4x4 vehicles, Pickup Trucks, ATVs, and many other types of off-road vehicles.
Document 9: SEAT Ateca: SEAT Ateca is a compact crossover vehicle (CUV) manufactured by Spanish automaker SEAT. It is also the successor to the SEAT Altea.<nowiki> </nowiki>The Ateca debuted as a concept vehicle, the SEAT IBX at the 2011 Geneva Motor Show followed by the SEAT "20v20 Concept" in the 2015 Geneva Motor Show. The car is named after the Spanish town of Ateca in Aragon.
Document 10: Volkswagen Country Buggy: In 1967, Volkswagen Australasia Ltd. started with a project vehicle designed for Australia's rough conditions. This vehicle, designated Country Buggy or Type 197, was designed by project head Volkswagen Australasia's Managing Director Rudi Herzmer and VW Engineer Cyril Harcourt in VW Australia's Clayton factory.
Document 11: Dune buggy: A dune buggy or beach buggy is a recreational motor vehicle with large wheels, and wide tires, designed for use on sand dunes, beaches, or desert recreation. It is called a "Beach Buggy" in the United Kingdom, Ireland and many other English speaking countries.
Document 12: Jeep trail: Jeep trail is a term originating in the United States to designate unpaved roads designed and maintained for use solely by high-clearance four-wheel drive (4WD) vehicles, regardless of the vehicle manufacturer. Only the more difficult unpaved roads are considered jeep trails while gravel or dirt roads passable in conventional vehicles are simply unpaved roads. The word "jeep" in this usage is normally spelled with all lowercase letters, the brand name of Jeep being just one of many that is drivable on difficult road surfaces.
Document 13: Citroën C-Buggy: The Citroën C-Buggy is a concept car presented by Citroën in May 2006 at the Madrid Motor Show. It is a two-seater city car, with Dune buggy and SUV styling influences. It is made with some protection against off-road grievances, such as slightly raised suspension and a sump guard. It has tinted glass inserts in the lower body side panels, and no doors.
Document 14: Street-legal vehicle: Street legal or road going refers to a vehicle such as an automobile, motorcycle, or light truck that is equipped and licensed for use on public roads, being therefore roadworthy. This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads therefore do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road (such as a sandrail) that is trailered to its off-road operating area, and a race car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street legality rules can even affect race car helmets, which possess visual fields too narrow for use on an open road without the risk of missing a fast-moving vehicle.
Document 15: Screw-propelled vehicle: A screw-propelled vehicle is a land or amphibious vehicle designed to cope with difficult snow and ice or mud and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving. Modern vehicles called "Amphirols" and other similar vehicles have specialised uses.
