Our X got hit by someone when it was pretty much brand new at ~2500 miles. The damage was small, a dented panel on the FWD. Their insurance covered the entire cost without incident. Ultimately the bill that went to insurance was $8k for the replacement panel, taking the door apart enough to put the new panel back on, and then repainting the car and reinstalling the trim that had to be removed for paint to be done. So all-in-all a pretty minor bit of damage.
The insurance company, at our request, processed a diminished value claim and came back with an offer of $1500. On one hand, I'm skeptical since it was damage to a luxury car that was brand new. On the other hand, it really was only a dented panel. No airbag deployment, no frame damage, no damage to electronics, joints, etc. In my previous experience, this kind of body damage often doesn't even get pushed to a CarFax report.
Thoughts on if it's worth it to pursue independent appraisal of the diminished value and fight the insurance company over it? Anyone have experience with that?
