I currently have 44,152 miles on my 2008 X5. I recently had it serviced in June and had the oil changed, all fluids flushed (except transmission), new brake pads and rotors (both front and rear), etc., etc. So...I am good shape.

However, I thought that I would "entertain" the BMW sales person regarding the Maintenance Program Upgrade and Extended Warranty.

I actually called and spoke with a BMW Service Advisor regarding the BMW Maintenance Upgrade Program. He mentioned that due to the fact that I recently had my 5 serviced that I should not purchase the Maintenance Program Upgrade.

Regarding the CPO warranty vs. the Extended warranty...
They are both the same. Neither is a bumper-to-bumper warranty and do not cover everything like a new car BMW 4 year / 50K mile warranty.
