I can slightly agree but mostly disagree with the Marathon position. Before I sold my company I would not talk to used dealers or participate in any used equipment sales. If I did as a new equipment manufacture the used was all the clients wanted. When they found used they wanted my advice from me for of course free.
My disagreement is that Marathon spends a lot of effort to market used coach's and consignments, something I totally avoided in my marketing. The POG group has purchased a number of used units and we all could in the future including myself be a client for a used Marathon.
I would join POG if I ran Marathon, promote my coach's features and my service dept. Build POG brand equity and help maintain the desirability of my products.
