hi i am a new member,i love the ls400 and have purchased a cheap mk 2 as a starter and i love driving it. I will run it for a while and then maybe buy something better as i learn more about the car.I wondered if any members could comment as to which of the ls 400 models is the best one with the most reliable improvements,also i am curious as to why some models have the gold badge was this a de-luxe feature or just particular to one model?
