Short backstory: 6 months ago I had what I thought was a minor front end collision. Ended up not being minor - the frame rails were crushed and the frame needed straightening. The shop and insurance company have now gone back and forth for months, "unable to find the measurements needed to fix the vehicle." I just received a call that they're giving up.
I found this post: http://www.mye28.com/viewtopic.php?f=3&t=133740 regarding front end unibody measurements with a few diagrams but cannot find the "approved attachments" to go beyond the "rough check" numbers.
Here is a quote from the insurance company:
Can anyone help? I dearly love my M5 and cannot imagine it being parted out or wasting away. I should've come here earlier, but thought they'd figure it out. I am hoping someone can come through soon, as they've given me until the end of the week to decide.The issue is that there is no frame measurements for the vehicle. We need to replace the frame rails. BMW recommends using the Celette measuring system. There is no measurements for your vehicle. We have checks with Celette, no luck. We have checked with two authorized BMW shops, Autonation and Kuni BMW. We also checked with Pacific, another recommended BMW body shop. They cannot replace the frame rails, due there is not measurement. Metro also checked with BMW, no database for the measurements for this vehicle. Metro checked with a chief measurement system, which is a frame measuring system, not BMW recommend, and they do not have any measurement needed to replace the frame.
