Tobra - As I said in my reply Lex, Infin, Mazda and what have you are great car's I just don't want another Japanese car, it is just a personal choice, I have had good luck with both Mazda (RX7 twin turbo) and Acura (NSX) in the past just don't want another one right now.
I do not have rear seat passengers often, I think the S 60 is about the same interior size as a 3 Series BMW.
