The 66 Coronet I had years ago was a lot lighter. It was missing about the lower 3" of the rear quarter panels.
I didn't weigh mine either, in fact, the only vehicles I had any idea what they weighed was the trucks I hauled scrap in with.
The truck pictured weighed 4850lbs with about a 1/2 tank of gas and me sitting in the seat. Adding the snow blade on the front added another 300 lbs.
