I have one neighbor who is a "collector" and has various automobiles, trailers, tractors, riding mower, street light poles, a couple of old mobile homes/camping trailers and a nice 60' x 100' metal barn. His lot is heavily wooded and things are placed on over half the property. Most of the vehicles have all sorts of stuff stored inside them. Some are complete junkers but a few, if they had been stored better or caught before the oxidation and vermin did so much damage might have been worth some money to somebody. Supposedly the barn has some real nice old cars in it but ... pack rats are a huge problem here. Any vehicle parked outside unstarted will have them in it within three days. I lifted the hood of one of his vehicles and you couldn't see the engine because of the nest that had been built.
One day a couple of his nephews were on his property. We got to talking and they got very excited mentioning an old sports car in the far corner that was worth a million dollars restored. I kept a straight face and wondered if I could have somehow have missed a Ferrari GTO wedged between a couple of old beaters. So they took me back there all excited to show it to me. It was hard but I kept a straight face as the young men excitedly pointed to the "treasure". They were struggling to pronounce the name on the trim. I calmly and solemnly announced "Karman Ghia". "Wow, you know about these?" they exclaimed. "Well, guys, I'm older and when I was younger I saw a few of these on the road." They opened both the front and rear compartments. Both were packed with the sticks and flotsam that pack rats love to nest in. They finally asked me what I thought it was worth. "Well guys, it would be a labor of love for someone to bring this one back to life." "Were they fast?" "Well guys, they only have a little four cylinder engine in them so they weren't real fast." I was trying real hard not to burst their bubble but I didn't want to lead them on. I thought to myself if it were mine and somebody offered me $200 for it that I would ask how soon they could get it off my property.
As to how all this flotsam came to be on that property, I was talking with the owner one day. He revealed that he grew up dirt poor in an abusive household. He got a job reading meters for a utility company. As he did his job he would come across old stuff that people had. If they wanted to get rid of it, he would gladly take it and put it on his 11 acres. Cars, trailers, tractors, riding mowers, an old mobile home (that is now collapsing from rot and age), miscellaneous scrap metal. Where he found the old street lights is a real puzzle. I don't remember the dates on them but they are very old as in early 1900's. They are in good shape and really cool but I have no idea what anyone would use them for. All of this stuff is precious to him. He grew up with nothing so anything he has he treasures. He can be a cranky old SOB and a bit paranoid (or at least suspecting everyone means him harm.) I'd buy the 11 acres in a heartbeat if he were to ever sell it but it won't happen while he is alive. Having physical things means too much to him after growing up so poor. After he passes (he isn't in the best of health as in has an oxygen tank with him), it will be a real mess getting clean title to the property. I researched it after some comments some of his in-laws made. He has it titled in the name of some corporation that doesn't and never has existed in our state. A corp with that name did exist in a neighboring state but it forfeited its charter years ago and the owner was some female who lives on the other side of that state. What a mess. The attorney bill to get it all straightened out will be as much as the whole property is worth.
I'll try to take some pics when I'm down there this weekend. There's some cool stuff but most of it is in worse condition than the cars the OP pictured.
