You didn't look hard enough because Nissan, Mitsubishi & Caterpillar did not have a both this year either. Also, that study from 20 to 30 yrs ago might not be too valid anymore? I cannot speak to the return on displaying at Promat but we are North America's largest wholesaler & talk to dealers across the country & internationally. Our traffic was very high this year, not just at our both but at our facility as well. I still believe that Promat is a great avenue for dealers to sharpen their product lines and look to constantly expand and increase their profitability.
