Json structure missing "engineSize"

[Anton2k]

Hi, in the example documentation over on https://dvsa.github.io/mot-history-api-documentation/ the JSON document looks a bit different to what the API actually produces. I;m unsure if this is a API "issue" or that the documentation needs updating.

Is the "engineSize" accessible? when using the front facing web site https://vehicleenquiry.service.gov.uk/ I can input a vehicle reg and it returns a whole host of information that I think is useful, is there a separate api to obtain this info?

Thanks
