It appears that this vehicle had the option of coming with a 'Trip computer' to display "Distance to Empty", "Average Fuel Consumption", "Average Speed" and "Tripmeter". Is it possible to get one of these installed? If so, anyone know about how much that would cost? It's a feature I miss from the newer car I had previously. It's not going to kill me not to have it, but I'd be willing to spend some $$ to get it.
