Why was Lincoln Town Car so loved by older people? In case of any English error please tell me below! I'm still learning! 

One thing that caught me attention occurred yesterday, when I was in supermarket parking lot and I saw and old man that was with a certain difficulty to move and despite this, he entered in a Lincoln Town Car from 90s. In fact the majority public of this car was by old people. Why?

Well it seems a stupid question, ok, but since I know still not to much about the American car market (I just came from Brazil) I would like to know this. I suppose that other automakers such as Buick and Cadillac also had cars with similar public.
