Welcome to GreenHybrid! Wow... the third to respond. I'm slacking!
I had never seen a Prius, either, before I got mine. In fact, I was so used to merely looking at *pictures* that when I walked into my garage to find a brand new Prius, in that very first split second, I thought, "Gee, that's a really big picture of a Prius!"
Leather is not a factory option, but it is sometimes added once the car makes it to US shores. There are two XM Radio integration systems. I have installed
PriusXM. There's also
CoastaleTech, but I've heard many people are having trouble getting in contact with the owners.
