I finally got hold of the service guys at BMW of Austin and asked about the car. I'm not sure if the guy I spoke to is fully aware of the CPO transfers from third party dealers, but he said the warranty all be transferred to me. And it is valid till november of 2018.
If I get the car, I'm hoping my local bmw service honors the warranty
Fingers crossed.....
Will update you guys soon. I'm planning to take a test drive and see how the car is.
