We consider models of maximal flavor violation, in which a new scalar mediates large q{sub 3}{r_reversible}q{sub 1} or q{sub 3}{r_reversible}q{sub 2} flavor-changing transitions (q{sub i} is an i'th generation quark), while q{sub 3}{r_reversible}q{sub 3} transitions are suppressed, e.g., {xi}{sub 31}, {xi}{sub 13}{approx}V{sub tb} and {xi}{sub 33}{approx}V{sub td}, where {xi}{sub ij} are the new scalar couplings to quarks and V is the Cabibbo-Kobayashi-Maskawa matrix. We show that, contrary to the conventional viewpoint, such models are not ruled out by the existing low-energy data on K{sup 0}, B{sup 0} and D{sup 0} oscillations and rare K and B-decays. We also show that these models of maximal flavor violation can have surprising new signatures at the LHC and the Tevatron.
