My 2012 m3 is 74k msrp. 66k + TTL (which we will take out since you can't get the taxes back unless you trade in in certain states) so 66k. 4k miles later, I assume probably 60s is what I am looking at but dealer will try to sell the car at roughly 62-64ish.

That brings the drop the minute it leaves the lot at roughly ~10% however it doesn't drop much more than that until another year or so.

one thing though, it's relatively easy to order m3 500-650$ over invoice but I am sure there are not many that have actually got that deal outside of this forum and sometime even in this forum.

After typing that, there are too much to consider and an extremely important factor is the auction prices.
