QUOTE...he ONLY issues worth mentioning are; as with most KV6 engines it suffers an occasional rattle from the variable valves, depending on weather/heat of the engine/revs etc, this is purely only a cosmetic/audible issue and I actually purchased the vehicle with this sound as I knew the engines were prone to it and it has never bothered me and certainly doesent effect performance!
