Well...first off, BMW of Alex do not do the BMW extended. I mean you can but they recommend a third party they have a good relationship with.

Mine was I think $3900 for 4yr/50k on my previously owned E90 M3. (Total coverage of 8yr 100k)
The deductible is $100 per visit.
The coverage is great...I mean really excellent.
