most part, police agencies preferred the larger intermediate Dodge Coronet or full-size Dodge Monaco. A37 Taxi Package A Taxi Package was also offered in Dart's final year of production. Standard equipment included roof-light wiring, structural reinforcements in the body frame members, heavy-duty shocks and alternator and maximum capacity radiator. Engine options were the 225 slant-six or 318 V8. The Taxi package also included numerous interior upgrades including high-grade black vinyl, heavy duty floor mats, and heavy duty springs in front and rear seat cushions and seat backs. At extra cost, fleet buyers could specify a broader range of colors than those offered to retail buyers from the Production and Fleet Paint Selector, including Taxi Yellow, color code Y7. Dart Sport packages Convertriple and Hang 10 For 1973 and 1974, the Convertriple option on the Dart Sport included a fold-down rear seat/security panel offering of lengthwise space, and a manually operated metal sunroof. It was advertised as "three cars in one": an economy compact, a convertible alternative because of the sunroof, and a roomy station wagon alternative because of the fold down rear seat. The Convertriple was the basis for the 1975 Hang 10 option. It was aimed at surfers in an attempt by Dodge marketers to better determine consumer preferences in a declining performance market. Hang ten is a surfing expression for balancing at the end of a surfboard with ten toes over the nose of the board while riding the wave. Available only in eggshell white exterior with a factory-installed sunroof, the car's fold-down rear seat permitted the loading of a surfboard through the trunk. The Hang 10 option continued the surfing theme with various colored stripe material accenting the white vinyl seats and door panels. Orange shag carpet covered the back of the fold-down rear seat while the dash and center console had orange accents. Red and blue exterior stripes started at the quarter panels with a wave-riding surfer graphic. A surfboard design ran down the center of the hood. Between the taillights, the stripe pattern fattened into surfboard-shaped letters that spelled out "Hang 10." Caravan Tan In mid-1974, Dodge introduced the Caravan Tan trim package. Features for this Dart Sport included a desert-hued vinyl bench seat with multi-colored striped inserts and white piping, and gold-colored instrument panel, dashboard, and carpeting. Exterior color choices were dark moonstone, Sienna, gold metallic, dark gold metallic, golden fawn, and white. Spirit
