Sounds like Auckland on a VERY good day (Although the Beemers and mercs would reach about 40 each rather than 100's) and in place of the S55 AMG's 1 S55, 2 S8's and a 750iL and take away the Z8 and fewer M5's (maybe 3) and no XJ220's
.
But after seeing your list I am trying to stop myself buying a one-way ticket to Beverley hills
