"Used" BMW incentives and discount

I noticed that a lot of BMW dealers put their loaners up for sale. I assume the incentive still apply, and I understand there is a penalty on the residual based on the number of miles. Are there any other discounts available to consider when pricing such a car? In particular, I have noticed a few that have very few miles – they look like they were titled and then put up for sale. I assume that there is a reason for that. Anybody have any insight into pricing details on these cars?

This is mileage dependent. Has to be under 5000 miles (with rumors they may be changing this number).

Always ask about the fart count
