Hello, I am on my 3rd bimmer, 1994 540, I am now looking for a safer car, with side curtain airbags as I have recently survived a near death crash with a dumptruck that left my face with multiple fractures and I also have a mild brain injury, one more impact and the damage could be compounded and be very severe. SO... I need to know, what year did BMW start putting side curtain bags in the 3 series? I am looking for a 2001-2003. I am looking for a 4 door 330 or 325 (I am afraid I will be disappointed with the 325 power), or very possibly a Xi version. What are the crash test results of these models? What about durability of the X? Thanks!
