Thanks for the tip. That XF 8 way power seat must give a variety of adjustments to improve rear visability. My old 66 Vette has almost no seat movement, and you need a screw driver and wrench to adjust the seat back angle. Even a passenger side OSRV mirror wasn't a factory option in 1966, Although I added one, and four way flashers. Amazing how unsafe the cars were back then. I found out that the power windows will operate when the key is not even in the ignition. Children Beware!
