I've now reluctantly accepted that I won't be in a position to get a car this year, M or otherwise. Having spent a lot more on my wedding last year than anticipated and now trying to save for a house, it doesn't make a lot of sense financially right now (no less sense financially than her getting a huge extravagant wedding and diamond engagement ring mind you, but I don't know if that's a fight worth having...).

Realistically it will probably be this time next year at the earliest before I'm in a position to buy, so I am interested in what the market will look like then. My guess is:

E46 - Prices will continue to go up and clean models will be even rarer.

E92 - Prices will hopefully continue to drop and possibly bottom out by then. Maybe in a counter-intuitive way 2008 models will hold value slightly better relative to post-2008 models given the favourable tax treatment.

F8X - No idea... Based on current prices an M4 would likely be well out of my budget, but I wonder what kind of prices you'd be looking at in about 12-18 months?
