Looking to buy my first Harley. Looking at a 2007 Road King Classic with 17,000 miles. Great condition, some mods (both backrests, some chrome, pipes and intake). Bike is at a dealer. I just don't want to overspend. What price do you think I'm looking at? Should I try to get a warranty if there isn't a current one? Bike is currently 14,000. Thanks.
