Ownership History

From the seller: “I’ve owned this real 1973 Camaro Z/28 for the past 21 years, and it has been a solid, reliable driver that has been professionally maintained throughout my ownership. It’s the kind of car that’s equally enjoyable on the road or at a local car show, earning a People’s Choice Award at a spring show in 2024.

"The car has always been garaged, has never been driven in the snow, and is generally only driven in fair weather. I’ve accumulated more than 20 years of service records, along with additional receipts from the two previous owners. I’m only selling because my interests have changed, and I’d like to see it go to someone who will care for it as much as I have.”
