A 75-year-old Japanese man potentially has the finest supercar mancave in the world, having spent over 30 years building up an incredible collection.
Some people have collections we are all very jealous of, such as Jay Leno and his garage, which is full of all sorts of cars and vehicles.
But one man in Japan, who goes by the name Mr. Miura, has also amassed an amazing collection, featuring some of the rarest supercars on the planet.
Plus, rumors suggest that he once received an offer of $17 million for one particular car.
How did Mr. Miura build his supercar mancave?
Everything starts from humble beginnings, and this mancave was no exception.
Mr. Miura spent over 30 years collecting the cars he owns, slowly but surely adding to his collection.

The collector had always been a big fan of Lamborghinis and Ferraris, and they make up most of the collection.
Images on social media show a wide array of cars from the Italian manufacturers.

It is this car that Mr. Miura received an incredible $17 million offer for
The Japanese collector clearly has an eye for more modern supercars, too.
A Ferrari Enzo and Ferrari LaFerrari are two of the most modern machines located at his mancave.
This is where the car collection is now
According to some social media posts, however, this collection may not exist in its entirety.
Instagram user epicwin_f50 visited it in 2023 and reported then that Mr. Miura may have been closing the collection.
Other accounts, such as the CART Department, recently stated he has slowly begun to sell off the cars.

Any proceeds he makes from the cars, though, will be donated to charity.
There are some real gems in the collection, including the only Lamborghini F1 car ever to race.

Just as impressive is the supercar mancave they are located in, fully decked out with automotive memorabilia.
Diecast models are displayed in cases on the walls, along with some epic automotive artwork.
Hopefully, Mr. Miura can keep most of the cars we see here and continue to enjoy them.
