  We complete our search for MSSM vacua in the Z_6-II heterotic orbifold by
including models with 3 Wilson lines. We estimate the total number of
inequivalent models in this orbifold to be 10^7. Out of these, we find almost
300 models with the exact MSSM spectrum, gauge coupling unification and a heavy
top quark. Models with these features originate predominantly from local GUTs.
The scale of gaugino condensation in the hidden sector is correlated with
properties of the observable sector such that soft masses in the TeV range are
preferred.
