The Cadillac Catera is an export version of the Opel Omega MV6. All U.S. Cateras were built in Germany in Russelsheim near Frankfurt/Main. Opel, the German auto manufacturer is owned by GM. It's shame that Opels aren't sold here, in the U.S. since GM owns the company. Well, at least I have the chance to drive my OPEL OMEGA (Catera).
