Looks like typo - in description is: The price is just £284.99, plus £12.99 shipping to anywhere in the UK mainland.
What is surprising is number of sold - 1
I wonder if someone really bought one for that price
edit: just logged into my ebay account - that one car was sold for original price, seller added that it's out of stock until november so it looks like he didn't want to stop listing just raised price to put off buyers
