I have also heard about Brazils high crime rates and that many cars are armored.In fact i had seen a picture of a modified BMW(not armored) with....a flame thrower under the car at the drivers side.If a thief tried to highjack the car the driver would press a button and flames would burn the thief!!Honestly!
I believe Ronaldos X5 was stolen in Brazil but was later abandoned.
Anyway,i think it is quite stupid armoring sport cars.If he was driving a Ferrari would he armour the Ferrari?And why is he carrying weapons?AK 47 and magnum?
