I think it's a beneficial change, we have over 5,000 vehicles listed simply as Honda Accord so anything that can break that down a bit more is beneficial. Furthermore in some markets the Coupe (for example Europe) was actually a different platform and body to the standard Accord so it's useful to differentiate in this way.

I have noticed that certain cars (for example Cortinas, Minis and most weirdly Rover 800s where there were relatively few examples) now seem to have anonymously (the changer hasn't actually asked if or explained how this would be useful as dhill has) been changed to include the trim level in model name, so why not amend the Accord Coupes to have the bodystyle as part of the model name?
