Ok,I bought a Lexus IS 250c thinking is a high quality car. I should not have problems for the next ten years.i was wrong . Car makes a very annoying rattle noise from convertible top. I took the car to serramonte Lexus in Colma ,the technician said is a common problem with hard top convertibles it needs to be realingend,and put some shims to aliviate the problem,and can not guarantee it … will compleatly go away. He said it will take 16 hours of labor at $175 an hour = $2,800 or more to repair.
