We present a study of the decays B0bar --> D(*)0 K(*)0bar using a sample of 124 million Upsilon(4S) --> B0bar B0 decays collected with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We report evidence for the decay of B0 and B0bar mesons to the D*0 KS final state with an average branching fraction BF(B --> D*0 K0bar) = (4.5 +/- 1.9 +/- 0.5) x 10-5. Similarly, we measure BF(B --> D0 K0bar) = (6.2 +/- 1.2 +/- 0.4) x 10-5 for the D0 KS final state. We also measure BF(B0bar --> D0 K*0bar) = (6.2 +/- 1.4 +/- 0.6) x 10-5 and set a 90% C.L. upper limit BF(B0bar --> D0bar K*0bar) < 4.1 x 10-5. All results presented in this paper are preliminary.
