It really depends on your circumstances. If, like Avonside, you purchased a car in the US (with a US address), used it for some time, and then decided to relocate, then I think BMW will work with you and you have a good chance of getting a local dealer to honour the global 2 year warranty. On the other hand, if you are not a US resident and you try to purchase a new vehicle with the intent of doing a private importation to your home country, then you may have trouble finding a dealer to sell to you (see my previous post for the comments about non-export declarations), and you will be much less likely to get a dealer in your home country to honour the global warranty. They will likely tell you to forget it.

I think it really goes to intent. If you relocate, they will work with you. If you try to avoid paying the price in your home country, they will see little reason to work with you. Given the quantity of electronic devices on the vehicle, and the likelihood of failure, I would not want to have a new vehicle without a warranty, but that is just me. You can buy a private warranty if you are insistent on purchasing a vehicle in another country, but that type of warranty can be expensive, and it is a 3rd party, not BMW.
