Mines yet to be born yet too, but know that when it does, I'll have it set on the speedometer. My current drive only has a digital speedometer (quite big on the dash) and I find it dead useful, esp when using cruise control.
Current car also displays a seat belt indicator when you first switch the engine on for about 30secs. I find this useful too so I check everyone is buckled up, esp the kids. Does the GTi have same facility?
