I test drove a '97 LX450 today and it has this subtle but noticeable high pitched whine that goes up and down with engine RPM as you drive. The closest thing I can think of to compare it to is that whine you hear through your speakers when you have a bad ground in your stereo, except this happens even when the stereo is off. I also heard it in my '96 LC which I only owned for a month. Is this just a normal noise? Bearing in the tranny or transfer case? My imagination? Any help?
