Background: My wife's uncle passed away and left behind an overwhelming amount of stuff, three warehouse's full. He owned a couple drag cars, a few dirt bikes and was a gun dealer/licensed gun manufacturer so along came every machine you could imagine needed to remake anything you need. I think he put sons of guns to shame. The ATF took over a month inventoring what he had in stock. He passes away about a year ago and they just got around to the shed behind the house and while over there they let me take a look and I found this. It is an early 80's Suzuki SP500 (in case you couldn't tell) I am not sure exactly how long it has been sitting there but suffice it to say it's been a long while. I looked briefly at it, long enough to take a pic and sit on top to try and see if it was frozen up. I tried to gently push on the kick start but couldn't get it to move BUT I was dressed nicely and didn't make sure It was in neutral so that isn't a good indication it is frozen or anything. It isn't in horrible shape considering it has been inside the whole time and is covered in an inch of dust. She my wife's aunt doesn't have the tittle but she knows he had it registered so getting a replacement tittle won't be hard being family and all. The big question is what is it worth? She understands it is in ruff shape so I was thinking $300 but this will be the first bike I have actually owned in about 17 years so I am not good at assessing value. What are your thoughts?
