I think it's everything that is current over the past two year maintenance wise on the CarFax, along with the new AHC system. Plus the PO did some aftermarket mods, installed a hidden winch system. Eric said that they removed the winch system, and installed a brand new front end, and kept the winch system if I want it.
When he first told me about the LX Weds when I was getting the comps from him, I was a bit skeptical, only b/c I'm not a fan of the AHC. I own a 2004 LX470, and 3 months after buying it the AHC went out. I was able to delete the AHC from the LX470 and go about life.
I did some digging on here and after discovering that I could delete the AHC system on a LX570 if need be and install traditional 200 series L.C shocks & springs, so that gave me a piece of mind.
