Jim,

Fox will live as long as you and your customers are happy to use it.

IMHO Fox is a bit like my 2000 VW Passat Variant 4WD. Prior to that car, I updated vehicles regularly. But I've kept the VW for over 5 years because it is so reliable, does everything I need and is by far the most economic decision. Oh, I've had other cars since then- the best fun was an Audi A6 2.7T quattro we kept for a while in the UK- but the other cars have been and gone and still I keep the Passat. Sure there is a new shape. Sure there are incredibly cool new options. Sure it has a few dents from supermarkets and various prangs. But for my purposes- the VW is the smartest option. And I've saved tens of thousands of dollars by hanging onto it.

IMHO a lot of it boils down to perception. Some people need to drive the newest greatest cool-mobile. For them, the real costs of upgrading regularly are worthwhile, even if it means they can't spend the $ on something else. Others see a car as something to get around in. For them, cost is crucial and they hold onto the car until it falls apart around them. Others are somewhere in between.

Problems only start when one of these groups decides that only their viewpoint matters and the others need to be dragged kicking and screaming into the realities of life. Perhaps I should leave it there!
