A 3-year-old boy used his mother's computer to buy a £9000 car on the Internet auction site eBay.
The Sun reports that Jack Neal had logged onto his parents' computer, on which his mother's eBay password was stored.
The toddlers parents only discovered their son's successful bid when they received a congratulations message from the website about the bright pink Nissan Figaro.
On hearing the news Mr Neal called the seller of the car and explained the mistake.
"Luckily he saw the funny side and said he would re-advertise," Mrs Neal added.
The car, which has a 1 litre turbo-charged engine, had been imported from Japan and refurbished. It is available on eBay at a starting price of £7999 or a buy it now price of £8999.
