Lexus was building the first LS400's to a very exact price point. I know a few early owners, and their leather wore out VERY quickly.
The owners that stuck with the brand (almost all) have seen the interior material quality go up dramatically. Of course, in 1990 the LS400 was about $55K in Canada, and now it hovers right around $100K. It should be better.
