Are mileage and other specs shown in US units only?

Mileage on the storefront is shown in miles ("mi" / "K mi"), and asking prices are USD. Other specs (seating, year, make, model, description) are whatever the seller entered. *There is no kilometres toggle and no litres/gallons converter. If a non-US vehicle was entered in miles, or a description uses local terms, that is the seller's content — confirm with them.
