Info on jbl paragon

Hi, I have been talking with a guy who just got a 1963 jbl paragon. This guy does not know much about hi end audio stuff, neither do I, but I am learning. I am not going to see it untill first week of may. but he wants 3000.00 for it, all the info I have on it is that it is 11 feet long, He said it was in pretty rough shape. I have no idea if it is worth going to take a look at, the only reason I would buy it is to re-sell it. Is it worth 3000 if it is in rough shape? Do people spend money on just the speaker components inside? or does the cabinet make the value? any info would be great Thanks
