While it may be known as the Caddy that zigs, the Catera is much more than that. Designed as an entry-luxury vehicle, Cadillac based its Catera on the superb Opel Omega MV6. Opel may be best remembered here for its Kadette compact and Manta sport coupe exported to the U.S. in the early 1970s, but Opel is considered one of the top automakers in Germany where it continues to produce world-class luxury sports sedans.Already established as a solid contender in Germany, Opel's MV6 had all the basics in place before the Cadillac and Opel engineers went to work.

The result is a car that can stand up to close scrutiny.Click here to read more
