Some figures I gathered back in 2003 from the books and net. This is in the earlier discussions on the lend lease.All are quotes from sites or books.:

The Soviet Union ended the Second World War by having over 650.000 trucks available for use. Of those, 58% were Soviet in origin, 33% British or U.S. and the remaining percentage captured from the Germans.

Lend-lease aid amounted to approximately 10-12% of the total Soviet war production effort. While this does not seem like a significant amount, having 10% more key supplies available could make the difference between holding the line to going on the offensive.

-----------------

Soviet historians have typically denigrated the Allied efforts to supply the Soviet Union with war material as paltry in comparison with her own production and that it was not essential to the Soviet victory. In armored fighting vehicles this is somewhat true, in aircraft less true and in raw and semi-finished industrial materials this is a bold-faced lie.
