I got $24K as a trade for my 3.0si coupe with 15K miles. Identical specs to Hawkeye's car otherwise without the aftermarket parts. This was fully $2-3K more than I was quoted by two BMW dealers and Carmax, and since I only pay tax on the portion over the trade in IL, I considered it a pretty good deal.

Most of the Ms selling at dealers below $30K either had high mileage, an accident record, spotty service, or cosmetic issues. You can occasionally find a good deal from a private seller here. I was able to talk to a private sale in Chicago down to $28K for a car with 20K miles, and I think the car was later relisted by a dealer for $30K (he ended up trading it in). If you weren't too picky about the options (no nav, no extended leather), it would have been a pretty good deal.

Most BMW dealers I dealt with weren't willing to go below $31-32K for a 07 M with around or under 20K miles. With CPO I was looking at between $33 and $35K.
