2000 Cadillac Catera Reviews

Rated
based on 4 customer reviews
The Catera is a Vauxhall/Opel Omega built in Germany. Read the European reviews and you do not find the problems experienced on the Cadillac badged Omega's. Could it be that American mechanic's/technicians do not have the expertise to repair or maintain them?
I love this car, ride, comfort and handling, and I fix it on my own, I don't trust this car to anybody. I had 4 cateras, and 3 of 4 I got in horrible shape. People never took care before, drove till brakes down, and then it costs a lot to fix at the shop. My last one was taken care pretty good, a lot of things were replaced, even so, job was done not professionally, timing belt was installed in...
