While I believe the true market value may be less, I've seen some pretty strange things on ebay. On the other hand, I've got some exceptional
steals I mean "deals" on ebay.....the rear fender and streatched bags, LED tailights, etc. off of an 09 SERG for $1200.......also a set of 09 CVO Chrome Blade wheels with tires and ABS bearings for $1,000.
You just never know. You might do as the dealer suggested, if you're not in a hurry......some people have more money than brains and they want what they want right now! Look at the rediculous mark up that some dealerships get on their stock new bikes.
And, if worse comes to worse and you're just not willing to take as little as $2k for the motor......just keep it for a back up motor. There's value in that as well.
