What is the cost and time to fix a minor rear end

so this afternoon on the way home from the shop, I am waiting to enter the traffic flow into C R Swart from Kelvin str in Kempton, when I hear massive brakes and locked wheels, screaming, followed by (what felt like a massive) Impact.

So there we have it, 49 1/2 years accident free history now stuffed, and it wasn't even my fault.

The damage doesn't "look" major, but I am sure it will still cost a bit to repair.

@ LZ,
1)What is the procedure to follow now, we got the traffic police to take our statements etc, and they say report and case number will be ready in 2 days time.
2)What is the cost going to be...approx
3)What is the downtime without my "daily drive" going to be
4)Do I get a stby vehicle if the downtime is excessive (2-3 days)









I am feeling a bit hurt that my "baby" had to get some trauma on her

I was amazed at how much more the "bull-bar" was buckled and at how "solid" the BMW is.
