Having experienced the BMW extended warranty I would recommend to anyone with a 2-4 year old car to invest in the warranty for peace of mind. While it wasn't nice to have constant problems with the car, every step of the way dealing with the warranty was fantastic, or putting it another way, I didn't have to deal with them, the process was seamless. I would have preferred not to claim a single penny though, I bought the car to drive not sit in a workshop. Thankfully I have not needed to make a claim in over a year, ironically since I started to pay for the warranty myself.
