i've never seen a real one, only ones reviewed on TV and video but the head-up displays that show info in the windscreen like on the BMW M5 i think is a much cooler and more useful feature than a colour display in the dash. having speed and revs showing in a HUD means you wouldn't have to refocus your eyes as much looking at the physical dials on the dash, keeping your eyes focused on the road more. considering the amount of sophisticated options you can already get on VW vehicles like DSG, ACC, rear parking camera, seems a let down not to have HUD, unless somehow BMW have some kind of expensive patent on it or something?
