Those bike are awesome. I would be curious to see what they bring in Manhattan. Around here, about 75 miles west of Manhattan they will not really bring much. For example there is a fully restored, pretty spotless Continental from about 71-72 that has been sitting in a (fairly obscure) second hand bike store at $55 for about a year right now...
That Sprint is stunning and at around 32 pounds is probably the lightest of the bunch, but these guys need some muscles to carry them up the stairs.
If your guy has a 1965 Super Sport in 22" or a 1965 P11, P12 or P13 from 21-22 inches, super please let me know
