According the land lease terms all the equipment shipped to the USSR during WWII had to be returned to the US after the war if not lost in fighting.
But according to some memoirs of Russian sailors, the cars and trucks after being loaded to American transports were drowned in the sea in the sight of the Russians.
The witnesses allege that the Americans required the equipment being in excellent state, well painted and oiled so that the Soviet technicians had to make good efforts to bring the equipment into desired state, yet all the work was obsolete.
Allegedly after such cases the USSR refused to return some equipment and opted to pay for it.
Is it how the things were in reality?
