How many EXIST??????????

My question if it is ANSWERABLE!!!!!!!!!!!!!!!!!!!!!!!!

How many of the 1987 E28 535i actually still exist and how many of these actually made it to AUSTRALIA.................... Of all the driving around I have done, I have spotted many 3 series of the same model and to date ...............1x525...............
Apart from my 535i, a friend has the only other so far...... (his is dead and off the road)....

This is my ride....................... nothing flash................. just a great catch at $500 +RWC

Thanks and keep cruising
