I just purchased a used 1993 SC300 with 47,000 miles. Mine is also like new and has been serviced regularly. I have found that the passenger seat will not go all the way forward or back. It will move slightly and then start to twist rather than contimue in a straight fluid motion. Before joining this forum I found several old postings on the "little white disc" in the gear assembly. I will be taking my Lexus into the dealer next week to get an additional key made and would like them to look at the seat, but.... I don't want them taking advantage of a "helpless woman" so I am trying to gather as much info as possible. Thanks for any help. Rhonda
