I was one of the top salespersons in a large Harley Davidson dealership, and for about 3 months at the largest dealership in Texas.
Most of the customers are older folks, that have older tastes and actual credit. Harley Davidson markup is obscene. On slow mid-week days I've cut some deals where the buyer was ecstatic, and myself, and the dealership still made several thousand dollars. That, combined with poor management is why Harley Davidson has brand, and money woes.
Younger folks have less credit, and have found that they can buy a better motorcycle, cheaper elsewhere.
