Or maybe they need a new lineup completely?
Think about it, most people aren't gonna go for this new TF because simply you can pick up a mint special edition one for half the price.
If they were like other manufacturers producing cars constantly they could refresh their line up and people would go "ah the last tf was good, lets buy the new one" - Quite simply they need a different set of cars and a new image to even have a hope of working in this market and economic climate
