Cannot tell from the ad or pic if it is a Bonneville or Catalina. https://denver.craigslist.org/cto/d/aurora-1980-pontiac-station-wagon/7219366559.html
Looks like it used to have wood molding on it, that would make it a Grand Safari (Bonneville) . And it has the Bonneville style front turn signal covers, the Catalina ones do not have the 2 spears in the center.
This would be a Bonneville Safari. They dropped the 'Grand Safari' name after 1979. I don't believe you could order the wood grain on the Catalina model for this year (and '81 as well). It was standard on the Bonneville, but there was a delete option' as well. Seen pics of a couple '80 - '81 Bonneville Safaris without the wood.
Also doesn't have the towing package due to the snowflake rims being 5x4.75. Definitely a Bonneville Safari due to the present (and missing) trim.
If anyone here buys it I have a passenger headlight bezel, even though the fender looks damaged as well.
