I just had nearly identical damage repaired on my S, for the third time. Yes, our S has been rear ended three times, all three times at levels in this range. One caused a crease in the hatch lid, but the other two were bumper only, with no underlying damage. Those two were $1200 to $1600 or so at my local Tesla approved body shop.
For the wreck that just occurred at the end of January, we had to wait about three weeks for replacement bumper parts to arrive. The most recent time, since the damage was all cosmetic, we persuaded the insurance company to pay the body shop to reassemble the damaged bumper and let us drive the S for three weeks and take it back for the three day repair when the parts came in. Since that saved them three weeks of car rental, they were agreeable to the idea.
