I am the second owner of a 2003 SC430 now with 42,500 miles. The seat cushions of both front seats have lost their support ability and the leather is stretching. The in-service date on the car was Jan, 15, 2003. I bought it from a Toyota dealer on Feb 6, 2007 (40,462miles) so it's out of the basic warranty period. I haven't taken to a Lexus dealer yet but I'm trying to understand my options for when I do. Anyone have any advise? Thanks
