I think your on to something here about the M5. The M5 really isnt for the older crowd because the ride can be a bit harsh. Ive driven it and I honestly cant complain about the ride or the shifting but then again Im 18 and that stuff doesnt really bother me. In fact I thought the M5 was comfortable however I'm not a Mercedes buyer like many M5 buyers are. I think that those who complain come from driving Mercedes and Jaguars and tend to be older. Yet there are still many older people who love the M5 so..
