These bikes aren’t rare or hard to come bye how and why do you feel your 13-15 year old bike is worth 3 grand less than when it was brand new on the dealership floor???
I am still dreaming and window shopping but am acutely aware of the attempted fleecing performed by used vehicle owners. Thus I am completely with you. But we also must take inflation into account before doing any comparison. I used an online inflation calculator and looked up the MSRP of the bike. So here are values from 2006 converted into today's dollars:
2006 dollars MSRP $11,099
2019 dollars $13,824.59
Let us say the owner made the purchase at a Discount of $2k:
2006 purchase price $9,099
2019 dollars $11,33345
So everyone can apply their personal used vehicle standard depreciation against the current dollar values.
Something to factor into that: A magazine article did a comparison and several of the bikes in the 12k range today (in addition to being much better) were something like $1500 cheaper than similar bikes in 1999, after factoring in inflation. So like some here who decided to purchase the brand new bike may have perceived, if the owner of the used bike refuses to adjust for this reality, the new bike becomes a much better value.
Lastly, markets vary so much. In the south there are some great prices throughout. In the Midwest US bike prices, from used to new, are sky high. Someone must be getting those prices, right?
