On certain road surfaces my 2011 Sport suffers really badly with vibrations to the point that it makes my ears feel really uncomfortable. What are these models like on the motorway? I want to visit my friend but I don't think I could do the journey if my ears were to be subjected to the awful vibrations for the whole 2 hours! We have at east 3 roads on the Island that are particularly bad. One is worse on the outward journey than the return for some strange reason!
