This seems to be the place to do this kind of testing: https://adwords.google.com/select/AdTargetingPreviewTool

As far as I can see this seems to be a reliable presentation of your actual ranking seen from a given geographic location.

It would have been nice though, if you could easily extract your actual position as a matrix on various markets. The above tool requires you to manually look through a number of pages to locate where your website is located, but it does the trick :)
