I made the choice to get a new 2016 LC over an LX. The main reason? Price. I couldn't justify spending basically another 20K for a Lexus badge, power folding seats, and air suspension. I previously had a Range Rover sport, and I don't think I would go back to another "flashy" type of car again. The air suspension will fail in <10 yrs, the 20" wheels make the vehicle less capable in non-pavement situations, and cost of every single thing to replace or repair is higher. Also the LC is much more reserved, and only cool people will know how awesome your truck is.
It's not air suspension in the LX. A vast majority of the (nearly 20 year old) LX470s with the old AHC system are still running strong with little to no issues. I'm sure the new 200-series AHC system is even more robust. And $800 you'll have a set of rock warriors, sell the 20s for profit.
