The only other one that I can think of that matches your description is Beck's that used to be in Scottdale. They had a small lot in town and probably 150-200 cars out in barns and on the grounds of the owners farm outside of Dawson. They operated until the very early '90's if I remember correctly. I don't know if the owner retired or just got out of the business, but overnight the cars just disappeared. Rumor has it that they were bought out in one large lot for a ton of money in 1990 standards by a collector. Others say that he sold the property with the cars on it and the new owner scrapped them all. If that was the case, it would have been awful. There were many sweet cars sitting out in those fields ranging from the mid 40's through the early 70's. Mostly Mopars, but a few Fords and GM's mixed in.
Side story on that dealer. They had a green 70 Charger 440 RT ,727 floor console, etc. sitting in the weeds down there for probably 10+ years. I must have stopped there 2 dozen times from the late 80's to early '90's trying to buy that car. When they first got it in, it needed a drivers side quarter but the rest of the car was solid. By the time they closed down, it was pretty much rotted away. Every time I stopped, the answer was "No, I'm going to restore that car for myself". It's probably long been parted out somewhere by now.
