The Butler Corporation’s “Guarantee Buy-Back Program” provides customers the opportunity to trade in or cash in their 15-year-old or newer Butler System/van at any time during ownership including while financed or leased. The buy-back amount for a used Butler System and van may be as much as 75 percent (or more) of the original purchase price. The buy-back program provides our customers with an easy, convenient way to keep their equipment updated with the latest technology and warranties. Information available upon request.
