Concord Mixtee
 

I have the opportunity to buy a shiny old Concord Mixtee. It is good working order. I replaced a rear derailleur for the owner with a matching unit from the parts bin. Should I buy it or let someone else? If I do buy it what should I offer?

My experience with concord has all been on the lower end of things. Still, the ones that have passed through had chrome forks and really cool head badges. All have been hi-ten tubing but they did make some better models. Assuming yours is similar to the ones I have seen I $30.00-$75.00 is fair depending on condition.

Unless you mean Concorde, then you are in another ballpark.
