A Heads Up Display would be nice. GM already has the technology and implementation down from the various GM cars that have (had) them. I have a Grand Prix with one now and can't imagine driving without it. I was sad to see the new G8 (Aussie Holden Commodore) doesn't have one.
Having to move my head and re-focus my eyes to check speed, radio station, etc when I drive a non-HUD car reminds me of how great the HUD is. It's not that I'm totally lazy, it just seems dangerous now when I have to search for my speed instead of just having it within my field of view while still looking at the road.
Anyway, I can't imagine it costs much; it's really a reflected LCD display. For a car that seems to be aimed as much at high-tech people as tree-huggers this seems like a no-brainer option.
