Well the advert that is displayed when I visit this thread is from Evans Cycles
"Trade in your old banger for up to £100 off a new bike".
The power of google ads I guess
I suspect she would want more than £100 for it though.
Don't know the Specialized women's bikes well but I have a Specialized Rockhopper which is a hardtail MTB and from the price I suspect they are of similar quality and equipment level. But if I wanted a full suspension equivalent of my Rockhopper I wouldn't be surprised to have to shell out near £1000.
For a full suspension for the same price as my Rockhopper, I would expect a significant drop in component quality.
Selling bikes second hand for a decent price is difficult. Everyone wants a bargain. Stick it in Friday Ad and you get people who don't understand why you are trying to sell a basic hardtail for £250 when they can get a brand new full supension with disk brakes from Tesco for £99.99.
Firms like Specialized sell like football shirts - they change the colour scheme every year so people can tell whether you have the latest model. If like me you are not bothered then you can usually buy last year's colour scheme brand new at a significant reduction. So if you bought the latest brand new you are hit twice, once because it can be bought brand new for heaper and once because it is second hand.
I imagine you would be looking at £200-£300 if you can fight the right buyer.
Cheers,
