OK, I get that. I guess what I was originally getting at was that I really like the look of the C5, with its solo seat, but I could see occasions when I'd want or need to have the ability to take a passenger somewhere (kids to school or to dance class, for example). I'd remove the pillion when I knew I wouldn't need it.
I guess I'm also coming to think that even with the pillion seat, I like the look of the C5 with it to the look of the G5 altogether.
