Old high end stuff replaced with new low-end stuff is always a tough call. Obviously this is not a collector as-is, but I think it would be a very good bike for someone getting into racing or triathlons, especially considering the small size. This is something I'd buy for my girlfriend. If you market it as such, I agree that it could get into the $300 range. Sora/Tiagra doesn't make it worthwhile to part out. Same for the wheelset.
