Thanks for the info, mdude. I had noticed the quilted leather on the 16s, but had not known about the touchscreen. I'll note that down for consideration.
Yes, I think I'm noticing a pretty good abundance of 2015s on the market, but practically no 2016s. I was assuming it was too early for them to be coming back on the market, but now that we are looking right at 2018, one- and two-year lease units should be showing up.
And you are right--I've seen no 2018s on sale or any literature on them on ebay, so I wonder if there will be any.
I'm pretty well sold on the K900. It's just a matter of running across the right one at the right time. Now, mind you, my car buddies mostly started howling like dogs in the night from the time I mentioned "Kia." One of the, who is a Lexus LS owner, says there's no reason not to get one of those. I mentioned the approximately $20,000 price difference vs. an equivalent K900, which I think is a reason. Another one just basically said, "Anything else. Jeez." Only my mechanic, who's an amateur therapist (I think all the good ones are), said, after I told him I was dreaming about K900's, "F-- it, buy it. There's no other cure." I don't think there is!
