It's one of those bikes where....As it sits? Barn fresh looking? flat tires etc... 5-7 range.
If the bike was detailed maybe? cleaned up big time? could pull a bit more...
barn fresh is appealing to many.....but often for more of a bargain price...unless its a
super rare and desirable bike. These are desirable, but quite common, especially in the color ...dark red/maroon
However you do it is up to you. If you want to do it right you completely take the bike apart this includes unlacing the wheels. Once the bike is completely in pieces there are over 400 pieces. I reuse all the pieces that came off the bike. Wirewheel all the hardware chase the threads. Wirewheel all the spoke nipples rebuild hubs. Travel to LBS for new tubes and tires, etc, etc. Search for replacement parts where needed. Spend time tracking a package of lost replacement parts in the mail. If you can bang them out in no time flat good for you.
