The issues you are encountering with the VW ID.3 seems to be part of an increasing trend where the model trim level / option specifications on the Motability website bear no correlation to what is actually on the vehicle manufacturers website.
As stated on the VW configurator;
Model shown is a previous version of the ID.3 Pro and Pro S variants, which is no longer available for order. New version of the ID.3 Pro and Pro S variants are now open for order. Delivery currently expected in Summer 2024. New version will include specification changes. Images may not match UK specification. Please consult your local Volkswagen retailer for more information.
Official electric range figures for the new version of the ID.3 Pro and Pro S variants open to order now, for delivery from summer 2024 not yet confirmed or available. Figures may differ from previous version shown which is no longer available for order. There are also changes to the engine power of the new Pro model, which may result in a higher insurance rating. Please consult your local Volkswagen retailer for more information.
The most significant changes are an improved larger 12.9″ central display screen, and on the Pro S (77kWh version) the option to add a Panoramic glass roof and it is now a 5 seat car (Previous Pro S version was only a 4 seat and could not be ordered with a Panoramic roof).
With regard to the options you mentioned (‘Comfort’ ‘Interior Plus’ ‘Exterior Plus’ ‘Interior + Exterior Plus’) these were all clearly listed on the previous version of VW ID.3 online configurator. As I mentioned above the issue is that VW have changed the specifications and the ‘Pack Options’, however the Motability website does not reflect these changes.
Your local VW dealer should be able to identify what is included in each pack by going on to their version of the VW vehicle factory order system as I understand the changes are detailed on there. The other option is to wait until Q3 in July and trust this has been resolved between Motability and VW. The downside of this is that some options have been removed and the AP may have increased.
