The D is not available here in the states. I think you'll find that the majority of us are US based and will not know much about these. I suggest UK based sites will know a lot more about these models. Not trying to chase you away here, but trying to help you get the info you need. Check out MiniTorque and TotalMINI. You'll find MiniTorque has no filters, the people on there can be quite harsh. TotalMINI is more social then technical.
