The cars estimated value is said to be upwards of £1million and include vehicles belonging to the Malaysian Prime Minister, an old F1 car, Bentleys, retro taxis, prototypes and even wooden replicas.
Ben and Eran are the YouTubers who run the Lost Adventures account and they went searching the building in Surrey after having it on their hitlist for a number of years.
The pair assumingly had a tip off as they revealed the vehicles were in the bunker as owners prepared the collection for auction.
Eran said in one of the clips; 'I'd had my eye on it for a couple of years, as it looked so interesting. We set out to explore the abandoned building with no idea what it was. We jumped down, only to find millions of pounds worth of cars underneath this place.'
The bunker had been used as a storage facility for Bristol Motors’ leftover stock with most of those cars still in there inherited from its Kensington showroom.
One of those with a high value was a Proton Perdana that had previously belonged to Dr Mahathir Mohammad, the former Prime Minister of Malaysia, who apparently sent to the car to the UK to aid in hybrid fuel research.
David Fletcher, the auctioneer tasked with selling off the collection, said the total value is somewhere around £1million.
