When i had brought my last IS200 about 4 years ago it was recomended by Lexus dealer (Twickenham i believe) that it was 6 years OR 100,000 miles which ever was he sooner.....
4 years on and with my 05 Plate IS200 When i brought it last year ..it was revised to 6years OR 60,000 miles again which is ever the sooner..
But to be honest if anyone has any slight know how with cars or any common sense when getting to 60,000 OR 6 years just have a look at the belts etc and inspect them ....if in doubt pop it in to a Lexus dealer & get them to check it over ( they wont charge you if they do it will be minimal ) and if all is ok then say to who ever the person is get them to put that in writing..... :winky:
