I explain it this way if I can log it , I can eat it . The setlimit thing is a detail and , if you think about it , is fungible . You can work with those limits to make CICO work . You have a daily limit or maybe it ' s not , because you have the sum of your limits over the past few and future few days . You can borrow from today and lend it to tomorrow ' s party . <| sep |> Everyone else summed up most of the pros and cons in their comments and I don ' t want to be redundant , but I do want to add that even though the 6 is more spacious , that doesn ' t mean the 3 is cramped . I just got a ' 15 3 iGT two months ago and at 6 ' 00 I have plenty of space inside it . In fact , even more than I do in my mom ' s midsize ' 08 Fusion . So 6 is roomier but the 3 definitely isn ' t small either .
