However all of the cars are said to run properly and were driven to the warehouse under their own power, with some taxed for road use as recently as 2016 - although others have not been taxed for three decades. Popular car enthusiast and YouTuber Freddie Atkins, who posts under the name TheTFJJ, was among the visitors on Monday and described it as a 'very special warehouse', adding: 'I've not seen anything like it before in my life.

They're all barn finds, they're all being sold here and are coming up for sale with London Barn Finds on Instagram.' Mr Atkins added: 'The scale of this place is just incredible.' He also said it was 'interesting seeing the varying states of the interior' and the cars gave an 'insight into what the interior looks like if you left it out for many, many years'. The cars, which have a combined guide list total price of £942,700, could be seen in a viewing session on Bank Holiday Monday - with no money changing hands on the day and all sales made by sealed bids after the event. The organisers said they would be contacting people who made bids following this open day and were still going through the offers as of today. They added that they would be putting any unsold cars up on eBay.
