Hi All, I have an IS200 SE with 68K on which I bought from Lexus with 58K on. I appear to have the famous clutch judder problem at low revs. I've asked at the local dealer and they say its normal for a car of that age (W 2000). As I have the extended warrenty does anyone know if I have a claim against it and if so whats the best way to go about it. Cheers Wayne
