I would say you just might make it into the totalled catagory. I also have a '97 328is and two years ago hit a deer on the interstate at 75 mph. I hit it so square neither fender was damaged and the nose was just high enough that the deer bounced back forward of the car. Everything from the thermosat housing forward was replaced and the total was $6400. Since you need fenders I put the figure at $7000-7500 or a bit more.
