OK, I need your advice. So I called two dealers today to inquire on extended BMW warranty and maintenance for my new 2006 BMW M3 coupe. Dealer A: maintenance upgrade: $2600 warranty: $3110 (100k/2 years August 2012) Dealer B: BMW warranty: $3900 years (4 years) maintenance $4700 for 2 years I am confused. Where can I find the MSRP and invoice cost of all extended BMW maintenance and warranty programs for low mileage BMWs?
