Now I can't resist a comment can I? I've had two ls400's for a total of 7 years, and they were great cars, no doubt. The LS430 however, is, (in my opinion) superior in almost every way. In those 7 years, I've experienced rust, starter problems, coil pack problems, wiper motor problems, suspension knock problems, damp boot problems, leaking power steering pump problems, air con problems, exhaust blowing problems, seat heater problems, display problems, a power steering rack leak, and that's just the things I remember. Oh, I nearly forgot the leaking sun roof. So as good as they are, the LS400 (unlike the Pope apparently) are not infallible. As I've said before, some of the known problems on the 430 can be prevented easily, and fairly cheaply. There are usually a couple being broken so parts can be bought for very little. For anyone considering one, buy one for peanuts, keep £1200 under your mattress if you really are worried about future air problems and have coils put on. Put in a new radiator for £90 to take away concerns of gearbox probs, and you'll have a superb limo and peace of mind.
