Sorry, to sound dumb. I've just stumbled across this article whilst just browsing the forum.
I take delivery of my 2006 IS250 next week from a Lexus dealer. I noticed the engine rattle on startup on the test drive, after a second the engine sounded really sweet so I just (stupidly) presumed it was because the car has been stood on the forecourt for a while and it was parked uphill. Will this be covered under the Lexus Approved Used Car Warranty?
