When i was going to college/tech school in the early 1980s three wheeler sales in the texarkana tx area took off due to one japenese motorcycle dealer ability to find a niche market for the things. sold serviced and accessory parts were aimed at the agriculture in the area. In fact the MFGR sent a team to find out what he was doing to make all the sales. ATV sales in this area accounted for about 30% of all sales in the US. What did the MFGR do, copied his success and allowed other dealers to bootleg atv units in his sales franchise area. Sold them without a service dept to back them up and expected him to do the warranty work ,service ,etc. He adopted a stance if you didnt buy from him take it back to whom you did. The mfgr didnt care as long it meant more atv sales. His overhead in parts ,service dept and general overhead was overlooked until he took a no service stance against the BOOTLEGGERS.
