I'm not an expert Mike ...... but from where I sit Univega's are not highly sought after. It doesn't matter if it has Campy parts on it ..... it's a Univega .... and Univega always reminds people of cheap bikes. I'm not saying there is anything wrong with this model at all, but when it comes to valuable vintage bikes .... perception is everything. I've got a similarly equipped KHS bike from the 80's ... a nice Coumbus SL frame, full Campy Super Record ...... but no one wants to pay much for a KHS frame. The parts though , people want Campy parts if in good condition with low miles. Some look for steals on a complete Campy equipped bikes like yours with, then sell the parts separately.
The hardest part of letting go of our vintage stuff is the memories..... but what purpose do these memories really serve? I'm finding it's more of a boat anchor than anything. Drag it here .... drag it there..... but I don't use it. I always tell people "use it or lose it" .... but I don't always follow my own advice.
