A cookie is a file on your computer that is sent by a web server to a web browser and is stored by the browser. The cookie is then sent back to the website each time the browser requests a page.
Cookies are either "persistent" cookies or "session" cookies: a persistent cookie is stored by a browser and remains valid until it's expiry date, unless removed by the user beforehand; whereas a session cookie expires at the end of the user's session (when the web browser is closed).
We use both session and persistent cookies on our website, for the purposes of storing the vehicles that you search for so that you do not need to search for them again next time you visit. We also use session cookies to ensure your user data persists throughout the time you are using the website.
