It is my understanding that if the property (the 2 trucks and the jeep) has been on city property for a long time, they have become city property. I think the tow company idea is the best, but who am I to say; most of my legal training comes from watching too much TV.
RE the Jeep, it is a late '40s Willys wagon with the high roof and is unusually clean. It appears to have very little rust; only modified fenders. Judging by where the cooling fan is sitting, it probably has the original 126 cid flathead engine that isn't worth more than scrap iron and a T-90 transmission that might still have some value; I sold one 5 years ago for $120. It appears to have the original springs, although they sit up nicely, and the right kind of lockout hubs to still have the original axles. Also, the width on the axles is right to be original. The sheet metal is awfully straight and the glass looks newer than the Jeep.
Here in Colorado you can get a 'Salvage Title' fairly easily, if you can show ownership. I have a '60 Willys just like that which I will title this summer, probably with a Salvage Title ‘cause it was purchased in Utah about 10 years ago.
They are real cool to re-power. The Willys I have now has Dana 44s under it that came out of a '76 Scout. My son is going to put a Ford 351 Winsor and a T-16 transmission in it. Around here, that vehicle, with some type of title, is worth between $1000 and $1500.
