I have no doubt that most Caterra's were POS but my father had a 97 that was completely reliable until he got rid of it 5 years later with 120k km on the clock. It did seem to eat through tires but at least GM covered 3 complete sets. Once they got the proper alignment specs the tire wear seemed to settle down. I took the Catera across the country and was quite impressed. It didn't have a ton of power but the V6 had a nice snarl, the suspension was somewhat buttoned down (euro style) and with the super comfy seats it was great at eating up the miles at high speed.
It probably blew up the day after he traded it in.

ps. If you are shopping Cateras the 97 is the one to get. GM did some serious decontenting through the years.
