Nothing can beat the 600 Mercedes for cachet though. Look at the list of owners: Idi Amin, Ceauşescu, Saddam Hussein, F.W.de Klerk, Papa Doc, Mugabe, Brezhnev, Tito, Mao, Kim Il-Sung, Ferdinand Marcos, Deng Xiaoping, Mobutu, Jean-Bédel Bokassa, Mubarak, Berlusconi, Pablo Escobar, Jeremy Clarkson, nothing will ever come close to that.
Ugly AF but artisanal and robust.
