I'm not completely sure, but I know our VIN's are mixed right in with the VIN's of your regular Proteges- ie. sequentially as they are built then assigned. So that database may not be able to differentiate between the different models. I saw this in a faq somewhere, plus when you call to get your production number, I know it is kind of a pain for them because they have to cross-reference several different sources. This may not be 100% right, but you get the jist of what I am saying...
