So unfortunately I had a side collision impact to my 8. The impact was on the left driver's side door panel. Does anyone know or have an estimated amount on how much a repair like this might cost?

If the damage is to the door only, you could get away with buying a used door in your colour. Assuming you're paying out of pocket, that's probably cheaper than fixing that door. Shop around at the wreckers?

You can keep your original interior panel if necessary.
