Well, the Sport has other appealing features on it (fog lights, a couple of other safety bits and pieces and so on), so it's really just one upgrade over what I would normally have got. I've considered just getting a separate navigation thing as well, but I'm told it's much better - in terms of keeping its value in the future - to have one that's preinstalled. I was wrong about the price differences, though - the slight upgrade to Navi puts it up by $2,500, and the Sport is a more reasonable upgrade. Aaargh.

I've heard the abbreviation "satnav" - I'm not sure where "navcomp" comes from. Possibly Star Trek.
