Just because they advertise the FSVT, that doesn't diminish the "uniqueness" or the "exclusiveness" of the FSVT. They still only produce limited numbers of these vehicles. IMO, the only bad thing that might come from advertising them is that they might be harder to find if you're in the market for one because more people know about them and buy them.
Now if they started to produce SVT models in a lot higher volumes... that would be a different story!
