Rear Quarter Panel Damage
 

A semi changed lanes into me in traffic on Wednesday and did a pretty good job of opening up my quarter panel along with banging up my drivers door.

I've seen a few threads where people have replaced the QP, that's what the shops I've had look at it have estimated along with some other sheet metal.

Has anyone else had this much damage repaired? I'm going to claim diminished value as well, any idea what I should expect from that?
