Anyone buy an extended warranty from API? The BMW extended warranty is only good for 2 years and is now up to $3,800 for a 3.o. I can buy the API warranty for 4 years upt to 100,000 miles for $3,000. I can buy this through my BMW dealer. It seems to be pretty close to a bumper to bumper. The plan is called Premiere with $100 deductible.
