Depends on multiple variables such as make, model, year, condition, amount of miles, etc. Which model are you looking to get?
Well, 3 months ago my friend's father bought a Cheif model (antique one). Was made in 1946. The price was around $26000.
Harley Davidson's are really horrid to ride in my eyes. Take it for a test run before you buy. and what model you looking at =)
They cost too much. You're paying for a brand name for which the value has been driven up by yuppies who want to look like badasses on the weekend.
I haven't kept up with the new prices lately as my interest is with the older models. The Harley I want is a 1996 factory softail twin cam 80 @ around 15k. My older one that I had to sell due to job loss was a 1970 sportster which I built from the ground up, what a heartbreaker to have had to let go of that sweetheart.
