My family had a ‘73 in Taupe Metallic (ugly color) and were excited when it was new. We really came to dislike it, however, as we much preferred our ‘68 Impala. The ‘73 had a horrible seatbelt warning buzzer and big red seatbelt warning light in the dash. The solution used by many people (not us) when this feature came out was to just keep the seatbelts permanently buckled and stuff the seatbelt between the seat cushions. Outsmart that buzzer! We finally traded it in on a new ‘77 Caprice which was a great car. Perfectly sized for a full size car and performed way better than the ‘73.
My parents had one in the early nineties.It was brown and had no pillars.The motor started smoking so my dad just drove it next the crusher at the wrecking yard he worked at removed battery and it was crushed.They were just considered disposable cars back then.
