Hi there I'm from down under in Australia.
I own two LS400s a series 2 1995 model, and a series 1 1992.
We go off Kilometres and not Miles over here but I thought I might add on this page.... my series 2 Ls has just clocked over 1,100,000 klms on the odometer!! equivalent to 800,000Miles!
and might I also add... it has a full genuine Original purchased from Lexus dealership service history!! not one service has been missed by the lexus guys for its whole life ! it still drives like it would of the day it left the showroom floor. original engine, never had a head gasket or anything done !!
