my much loved gpz250r

Recently my wife and i had our first child . my wife told me the bike had to go as riding was not safe. the thing is ive advertised it on bike sales and ebay but most of the potential buyers are learners dont want to pay the $2200 im asking because the bike is a 1985 model they dont understand that this bike is a fairly rare bike as it is the first of the ninja models not just a old banger so they dont appreciate that the bike is prob worth more than my asking price. would anybody know a place i could off load my kawa?
