the ls400 is a wonderful old car ,unfortunately the old word is the problem for alot of people,not so many good ones about,after all the newest ls400 is 16yrs old,the obvious choice if you want something newer ,and lets face it, to be honest,something more modern, then its the 430.im sure whilst they are more complex ,not every car has a suspension failure,we only hear of the problems,on here, there are im sure lots going along without too many problems
