It's all about finding the right buyer.
$3,250 doesn't sound high, if it is mostly original. If there is minimal rust. If runs and drives well.
Two places come to mind, for where to post it for sale.
First and foremost is www.earlycj5.com
Second would be www.g503.com
I'm sure there are others.
My best comment would be, make sure you get what YOU want for it.
