Some new questions : 

JavaScript

cars.updatePageConfig({
    offset: 2,
    limit: 10
});
can we also shortcut this way ?

cars.read({
    page: "prev",
    pageConfig: {
      offset: 2,
      limit: 10
    },
    success: function( data ) {
        // do something
    },
    error: function() {
        // handle it
    }
});

Another alternative : What about removing the "page" attribute and include a "action" attribute inside a "paging" block ? If paging block isn't present we implicitly know we don't want paging :

cars.read({
    paging: {
      action: "prev", //can be "next"
      offset: 2, //optional
      limit: 10 //optional 
    },
    success: function( data ) {
        // do something
    },
    error: function() {
        // handle it
    }
});

I think I like this idea but I have a concern. Would this permanently change the paging context or is this just a temporary change for a single read? I think it could be useful to have have this for doing things like jumping to a particular page, but I think it would be confusing if it didn't change that "global" page context. IMO, I think it would be better to only modify offset and limit in the updatePageConfig method and only allow a shortcut to turn paging off via read({page: false});  Any other opinions on that?

General remark 
Do we want to describe in the specs the following use cases ?

- Calling previous on the first page
- Calling next on the last page
- Setting an offset > total number of pages
