yeah C6 'vette (and maybe C5 from memory), current BMW 5 and 6 series. there's a few others to but they don't spring to mind right now.
now, back in time, some S13 Silvias had them, as did some U13 Bluebirds.
never ever seen an aftermarket unit, as it needs to be pretty well integrated with the car ECU and from memory the windscreen needs to be specially treated as well.
