What you are saying is very true - However - In todays market - its hard to find a buyer that is NOT looking for a steal...
then you have to post for sale - Where and how you do this is a big question
Then you have to answer the calls.. and a lot are looky loos or BS callers that want to get a big bargin.
Then there are those that say, I will be over tomorrow at 2pm - you adj your day and wait, never to see the buyer.
In posting for sale - now you open your self up to all kinds of 'people' coming to YOUR house to look at the bike and want to take it for a 'test' ride - then to offer you 'lowball' offers, again BS to deal with...
Yes, your statement is right - you will/may always get more if you sale it - but there is a "Cost" to You selling it.
Its your choice.
