The Specification section is directly related to the Technical Specifications for that same vehicle on your website.
This section is where you can enter specific information about the vehicle, from engine capacity and battery capacity, all the way through to the vehicle's insurance group, emissions class, fuel consumption and even boot space.
You will find this set of parameters after selecting to edit a vehicle in your Vehicles -> Browse Vehicles section.
The layout is simple and will largely be pre-populated for you. You can simply scroll through and enter information in any of the black fields or edit any pre-populated information.
The chosen specifications will directly influence the technical specifications shown on your website, as you can see below (see ULEZ & CAZ compliance).
In this example we have selected ULEZ compliant and Exempt from CAZ charges.
You can then see this reflected on the website listing for this vehicle.
