A couple of years ago I remember reading about £200 a month lease deals on Golf Rs, not sure what the deals are like nowadays but no doubt those deals had a big effect on the used market. Similar thing will happen with the M140i - I remember when I got mine I would hardly ever see one (or an M135i for that matter) but now I see 140s nearly every time I'm driving. I'm still on the FB group from when I had mine, people are really struggling to sell them at reasonable prices.
