The ls430 is a nice car, I've had 2, but my ls400 is more reliable, the battery on mine doesn't go flat if I leave it standing for 3 or 4 weeks, like Adam said ls430 aswell as having air suspension and compressor issues, it also has the vsv issue, rear doors jamming shut so they won't open, cd player stops working, rear subwoofer cone tears apart, vsc sensor issues on the rear, Windows clouding up, I can't think of anything else at this stage
