So Close
Before putting your credit card details on unfamiliar websites, always do your research first. You never know who could hack into your bank accounts or get access to other sensitive data. This man was trying to sell his car on Craigslist when a potential buyer asked him for a history report. He even sent the OP a link he could use to get the report for $30.
The OP had almost finished typing in his credit card information when he decided to quickly check out the website. Turns out it was only registered that day and was, therefore, completely fake. His quick-thinking saved him and how!
