Sold my '99 Sport... have new Civic Si. Selling all spares including:
Harbor Freight tire trailer w/box on back big enough for 2 helmets, jack, tools, etc and small box on front for car cover, chairs and other equipment. The trailer is in excellent shape and will carry four race tires. It pulls behind your Miata with no noticeable affects. The DeLan hidden hitch is listed below and can't be seen on the car when not in use.
(My family adopted Ry when his parents included him in an "all in bet" in the parking lot of the Choctaw Drive In. As I recall, in August, 1955. The winners of the bet decided he was more trouble than worth, a long-lasting personal character flaw, and we needed someone to cut the grass. Additional details on request.)
