Newbie Z

I actually got this Z in a field in Montana like I said 150 mile radius it was a 260 mile round trip, I'm located in Northern Idaho near Cour d Alene, Montana has a dryer climate and colder winter I can only assume that is the reason its not very rusty, both my 280s were purchased locally and where in much rougher shape as far as rust goes, only reason I am not abandoning one of the cars i'm currently restoring is that I am not very great with body work, welding in a floor pan or the battery tray dish of the inner fender or something along that nature falls in my skill set, reforming a rear fender is a little farther off my skill set,

So a couple months back I purchased a pair of 280z's! (I intened to have the best of both worlds, with a close to factory restore and putting a built V8 in the other) So far i've been enjoying the restoration process with both of them, minus the common rust problems and the costs of parts which I'm sure everyone deals with who sets out on this endeavour, So after calling every junk yard within a 150 mile radius and placing adds in local classifieds in the same radius. I located another Z (74 260z) that I intended to use for parts, it was located in a junk yard so I expected it to be in pretty rough shape, after talking to the proprietor and convincing him to actually look at the car (considering its a 4 hour round trip) and tell me anything he could about it. Basically it boiled down to driving 2 hours with a trailer in hopes that the car would be worth it, the body had damage and it was missing its motor/transmission which were not any parts I was interested in anyway, seeking interior trim pieces and small odds and ends that are costly and should be reproduced. anyway after haggling I talked the guy down some and came to an agreement, he dug it out of the tall grass in the field and brought it out to the lot, while strapping the car down to the trailer I took note to how little rust there was on this car like the usual stuff, under the battery tray in the fenders under the body and surprising there was nothing or minimal surface rust, the owner returned we exchanged money and started to fill out the paperwork the line for the vin # came up I climbed up onto the trailer and read the number RLS30-000134, I was shocked to see this low of a number, Now I have a 3rd Z and I don't know that I wanted a 3rd restoration project I know that people actively seek lower numbers for restoration projects and my original intentions were to get my parts and sell the rest of the car even send it back to the scrap yard if I couldn't sell it. so i guess my question is: What is this body worth? understanding its only worth as much as someone is willing to pay for it Should i hold on to it for a while and try to restore it down the way?
