I am also a new Lexus LS400 Owner. It is a 1990 with 180,000 miles on it with only 2 owners. I have a question about the rpms. When I am doing 70 mph the rpms are 2500. I would like to know if thats normal. I am sorry that I hijacked your post but for some reason the video on how to start a topic is not working. Thanks for any advice.
