so, having read all the replies, i guess the answer is no. we cannot predict vintage bicycle value... no surprise there... it is very subjective.. i want this bike, you want that bike.. their worth is a lot different to us... even if i find the bike i want, it has to be the right size to be worth anything to me... right bike wrong size = $0.00 to me... so, find your "deals", buy to ride, and let your estate worry about whether you made a good investment... they will probably all end up in a garage sale anyway...
