Be good to see this.
I've often thought of using the space for a touch screen, run it to a small PC in the boot or under a seat for a full 'av/nav/game' system.
If done well it could look very good imho. Could even run wifi on it to a router in your garage - so when you park it 'docks' and syncs MP3s and the like with a 'master' PC.

Never tried myself as I dont have the fundage to play with.
