So, just short of the price of Putin's gold toilet roll cover...
Gold plating is not expensive. I’ve had it before.
From your link “the opulent watercraft was reportedly estimated at £500 million ($6.6 million), although insider sources price it closer to £750 million ($990 million).” That doesn’t make sense. Did they mean $9.9 million or should the $6,6 M have been 660M?
Anyway, Cher is a nasty ho and I could care less about her opinions.
