okay i read the install for the auto up, a couple times, seems alittle bit tricky and a lot of hassel. i do want to have it, and i also want the auto up and down for my pass side. i know the uk cars come with it, but where and how much would it cost? has anyone here done this conversion? like swap switches or mod the ones it comes with? i was also thinking lexus' have auto up/down maybe swap switches with them?
