I'll post a picture tonight.

I agree withy this totally. I've done similar myself, except I wasn't smart enough to buy a $15 heat gun (I will now), but I used a propane torch as carefully as I could. I had a few rust thru spots in my floor when I changed the front seats ( I put in a pair from a 98 750iL, they're great) I had the carpet out and welded heavy steel brackets for the new seats, so I repaired a few spots where the floor and floor/pillar were bad. It really isn't so bad to do. Remember, it should be solid, but it doesn't have to be pretty. It's covered with carpet, paint and undercoating. I repaired the frame rail on driver's side too, and from time to time jack up the car on the section I repaired just to make sure it's OK.
Whether you repair or not is obviously up to you. I forgot who said this but..."If you think you can, you're probably right. If you think you can't, you're probably right"....good luck.
