landar,
i have a ls400'92 for the last 4 years and so far "almost" zero cost of repairs :)
LS400'98 it's a mark IV, so it should have all the problems of ls400 sorted out
and ls430'01 it was just a new model in witch they added alot more electronic gadgets,
that i'm concerned about, if they start to play up = cost :(
also there are more second hand parts for 400 then 430...
in european LOC forum there are alot of not so happy owners, when one considers value for money with 1998 ver.2001
and costs of maintenance/ repair/ risk of high bills...
i just want another LS that will not cost me much to run
