Those ^^^ prices are simply absurd. It took me about 3 hours with no lift and I had to reposition the car for every corner because of limited space. This was also the first time doing anything on an F80 so I wasn't familiar with it. A shop with a lift could do it in an hour or so. There are 3 nuts/ bolts to remove at the front and only 2 in the rear. $1700
If you were closer I'd help you out
