As for windshields... my wife and I both have Grand Prix GXP's with HUD's and we had to replace the windshield in hers a while back. We couldn't afford a new HUD windshield (high ins. deductible) so got just a regular one. We can still see her HUD fine, not quite as sharp as mine but still looks quite good and she uses hers all the time still. The only perceptable difference is when you look very close at the image... on mine it's completely sharp and single; on hers there's a faint 'echo' or shadow of the text at slight off-angles of viewing.
