I paid $1300 for the extended maintenance on my 03 E46 M3. At the time I needed front brakes done so it was a no brainer. And then I had the rear brakes done. And then I had the Inspection II with less than two months left in extended maintenance. all this was done after the normal maintenance warranty. Getting that inspection II done was huge, helped me sell my E46. I remember I had to drive a lot and really hard to get that service indicator down
The price does vary from dealer to dealer. My SA talked to the Finance manager and he gave me a deal.
Anyone know what the time/mileage limit is? after a point this is no longer available.
