Shopping cart positioning without a navigation bar

Hi, Im working on a white labeled car rent configurator, I've been told that I cannot place a shopping cart in the navigation bar as the content provided in the screenshots must be in its own section entirely. Where should I position the shopping cart on these screens to make it consistent? The following options I thought about: 1. on the top right, right next to elements ( Which makes it more annoying when responsive ) 2. Placing it on top of the section right above the top right element ( user will see less content because of it ) 3. Placing it bottom right ( Flow will be hard to read, people can mistake it for a "back to top button" ) Any solutions? I'm struggling here.
