a most remarkable collection of classic cars, and 48 of them went to auction in Sept 2015, and resulted in 24 million dollars

the residence was once the summer house of the king of Denmark

this 1914 boat tail model by Schebera Coachbuilders is just one of the cars in the 24 million dollar collection of Mr. Henrik Frederiksen

Wilhlem Maybach started his career as an apprentice to Gottlieb Daimler. He is credited with several Mercedes innovations still in use, the radiator among them.

Maybach outlived Daimler and went on to build V12 dirigible engines for Count Zeppelin and, with his son, formed an autombile company after WWI.

In the 1930s Maybach, like Mercedes and Packard, offered more affordable models. The Maybach SW-38 was one of these cars. Its Spohn design gave true meaning to the term “fitted luggage”

Dick Shepard probably has the greatest collection of Triumph motorcycles

While the collection contains at least one example of every Turner-designed Triumph ever made, it is also replete with rare and unique machines – the quest for one of which resulted in Shepherd meeting his long-standing “finder” Mike Jackson, a former director of Norton Motorcycles and a respected doyen of the vintage-bike world.

after more than 45 years of buying and refining – and a great deal of detective work to track down rarities – Shepherd is the proud owner of what is probably the greatest collection of Triumph bikes in the world: more than 320 of them.

He bought the only car Triumph Motorcycles ever made, which was called the Ladybird.
“The owner,  would only sell the car with the single-cylinder prototype bike that was the first machine to be raced at the Isle of Man TT by Triumph’s senior road tester, Percy Tait."

He also bought the most important motorcycle in the history of the ISDT, the only one to have won five gold medals, and went on to find the other three team bikes that competed alongside it in 1964, the Steve McQueen - Bud Ekins year, and so now has the full set.

Shepherd also counts among his collection the actual TR6 machine famously ridden by Steve McQueen in The Great Escape;
the supercharged, twin-engined Cyclotron on which tuning ace Fred Cooper became the first person to officially exceed 200mph on British soil in 1972;
 the TR5 ridden by Henry Winkler’s The Fonz in the television series Happy Days;
the Bonneville ridden by Tom Cruise in Mission: Impossible III (bought at auction in 2012 for £13,800);
 and the T100 that won the celebrated 1966 race at Daytona International Speedway when Buddy Elmore came from a seemingly impossible 54th place to take the chequered flag.

Michael Eisenberg, a Los Angeles collector of famous motorcycles, owns a few incredible motorbikes.

He owned one of the Captain America bikes (there are more than 2, Dan Haggerty restored and sold them after Easy Rider)

Eisenberg is well-versed in the memorabilia business. He supplied many of the motorcycles that decorate the Planet Hollywood restaurants, and once co-owned a Los Angeles motorcycle-themed restaurant with Fonda and “Easy Rider” co-star Dennis Hopper

Haggerty on the other hand, had a lot of problems after his popular tv show Grizzly Adams, even sold cocaine to undercover cops in 1988, and did 10 days in jail for tax evasion in 1985.

The gleaming stars-and-stripes panhead chopper with chromed hardtail frame is accompanied by three letters of authenticity. One is signed by the National Motorcycle Museum, where it was displayed for 12 years. Another is from Fonda and a third from Haggerty.

He has owned a few Steve McQueen motorcycles too, though I can't figure out why he buys and sells them. Just for profit I suppose, damn shame

Eisenberg, whose day job is selling high-end properties for Keller Williams in Beverly Hills, bought his first bit of McQueen memorabilia — a motorcycle that the actor owned and rode — 25 years ago and has watched it steadily increase in value. Actually, he’s watched it as it sits in his living room, much to his wife’s chagrin

Since then, he's bought and sold Steve McQueen's sunglasses, watch, and Chevy truck.
