I found this (I think the price is Canadian):
OAKVILLE, Ont., May 1, 2000 – Ford of Canada today announced it will produce up to 7,500 limited edition Harley-Davidson F-150 pickup trucks – 800 of which begin appearing in Canadian showrooms later this month at a suggested price of $43,295.
Are you looking at new or used? I assume used since you mentioned the Lightning and it has not been produced since 2004.
I would guess that they make in between 7,500 and 15,000 each year.
Ford-Harley co-branding partnership flourishes – with more than 60,000 pickups sold since 1999.
