Description
Is it a design choice for the add/update vehicles api endpoints to not contain all the fields? Specifically I was interested in adding/updating the image, purchase/sold info & fuel. Are you open to a PR for implementing the following fields?

- imageLocation
- mapLocation
- purchaseDate
- soldDate
- purchasePrice
- soldPrice
- useHours
- odometerOptional
- hasOdometerAdjustment
- odometerMultiplier
- odometerDifference
- dashboardMetrics
- vehicleIdentifier

I've cut the list down as some items didn't make sense to make available via the API (mapLocation, dashboardMetrics etc)
