I have owned a couple of those Bianchi road bikes, one darn near identical to the one the OP has shown. I find them to be, somewhat, unimpressive in machines, cosmetically and mechanically. That does not mean that there is anything wrong with them. Just unimpressive. As for value, I sold at least one for $200.00 CND a few years ago when the vintage road bike market was hot. My guess would be that had I sold it in Toronto, it might have fetched $350 back then. Today and I really don't have much of a feel for the strength of the Toronto market, my guess would be closer to the $250 to $300 price. Don't take that to the bank! It is just a guess and, as mentioned, my opinion regarding these lower mid-range bikes is biased. The uninformed buyer might go "goo goo" over the fact that he or she is getting a Bianchi which would probably positively impact the appearance of value.
