Depends on your area. Around my area here, roughly 5000 to 9000 Canadian pesos.
Not knowing the hours would hurt the price, so personally I'd push towards to the lower end of that.
Appearance also is a big factor for many buyers, so even if everything works, how faded does she look? Is there rust? What do the fluids and filters look like? What shape are the tires in? Even the condition of the seat can become an issue for buyers.
