Been shopping for a new to me LR3; today drove an '06 w/49K. First time driving the LR3. Around 65-70 miles an hour, steering wheel had some vibrations to it. Not severe, but noticeable enough that if I were driving it any longer than a test drive at that speed it would really bother me. Not sure if this is the vehicle (doubt it) or if it were particular to the LR3 I drove. To current owners-is this something that just happens in the LR3 or does this sound like another issue?
