I have a Verdigris Mica LS600hL on order, due in June.
At first, we had the Nobel Spinel Mica in mind, but we saw the green Verdigris at the dealer and chose that on the spot.
One of the optional features I most value is the radar cruise control. I predict that you're going to LOVE it. I use it all the time and, along with navigation, are the two features I now require on a car. Without the radar, the value of cruise control is much reduced as in light or moderate traffic you must continually fiddle with your speed.
Another comforting advantage of the radar is that if your attention gets diverted (it DOES happen), and you start approaching the car in front of you, your Lexus will keep your distance. It'll be interesting to see what happens in this situation, though, with the new-fangled driver attention monitor.....
This will be my third LS and this time I plan on testing a Lexus feature I've never used before: that of long term reliability. My previous two were traded in after 3 years, but I plan on keeping this one for 10 years or so.
