America's love affair with the MG began during the 1940s when GIs brought the cars home after driving them around the roads of wartime Britain.
US servicemen stationed in Britain during the Second World War loved being behind the wheel of their pre-war MG TB series vehicles so much they arranged for them to be imported home when the conflict ended.
The cars with the cycle wing front, upright radiator and prominent MG badge - looking not unlike the modern Morgan cars - began the MG invasion of America which ran until the company's factory in Abingdon, Oxfordshire, was closed in 1980.
Roger Parker, technical consultant of the MG Owners' Club, said: "These cars were very popular with GIs, who thought they were very quaint and very English.
"The American scene came of age after the Second World War and never looked back.
"There is definitely a market in America for MGs again. There is a strong following for them and they have been starved of product since 1980 but there is still demand."
In late 1945 car production resumed at Abingdon, which had been used to produce bomber components and other material during the conflict, with a new two-seater sports car.
The 70 mph MG TC was a mildly revamped version of the TB, with very few changes.
Mr Parker said: "Because of restrictions at the time, the only way they were able to get hold of the raw materials was if you were exporting. So the company decided to sell the cars to the States."
Next came the MG TD, an updated version of the TC, which laid the foundations of the marque's fame across the Atlantic.
The next leap came with the MG A in 1955 - a true leading edge design with a streamlined body and new push rod engine which comfortably allowed speeds of 100mph. But by far the most successful model was the MG B, which was launched in 1962 and was produced until 1980. Of the 500,000 cars built, around 350,000 ended up in the US market.
Mr Parker said: "When (British Leyland chief executive) Michael Edwardes decided to close Abingdon in 1980 it was said it was closed because of the exchange rates.
"At the time they were losing £500 per car. There
was also lot of problems for the engines which had to comply with different requirements.
"This meant the car went from 84 hp to 65, which meant it was a bit like pulling skin off a rice pudding. But they still sold."
Despite 1980 being the last time MGs sold in America in any great number the demand for the marque has never diminished.
"Even today there is a very strong MG following across the States," Mr Parker said. "They love the cars because they are very British, it is a quintessentially British and that attracts Americans.
"They love the adventurism and character of the cars. It is not like driving something inert, people enjoy driving them, especially with the hood down.
"It is a bit like with Warwick Castle - the Americans like the history of it all."
The fact MGs had relatively basic engineering meant they also appealed to people who enjoyed tinkering with their cars.
"They appeal to all kinds of people. MGs have been a bit like Minis in that they have never just appealed to one section of the community," said Mr Parker.
"We have have titled owners and salt of the earth people who love to get together. They all have something in common - their love of the MG."
