111 in (2,819 mm) wheelbase but with different sheet metal, the Dodge 3700 was produced until 1977 when the Spanish automotive taxation system was changed. The 3700 actually received the sheet metal from the Argentinian Dart, with certain modifications for the Spanish market. The rear wheel openings were larger and round, the grille and all lights were different, as was the instrumentation. The 3700 also came as standard with front disc brakes and power steering. A total of 17,589 units were manufactured of the earlier range (1965 to 1970) in Spain, they were produced as a SKD due to the protectionist Spanish regulations of those years. 9,959 Dodge 3700s were built until 1977, although the last new 3700 was only first registered in 1980. Although being the only large Dodge produced locally in Spain, previous American models such as the Coronet and Meadowbrook were exported to Spain ever since the 1950s with moderate success. The Dart and the 3700 were the biggest national production car available in Spain during all production years. It was an expensive luxury car with very low fuel economy by Spanish standards. Nonetheless, it was considered an economic car for its size in those few markets to which it was exported. In Switzerland, for instance, it was priced exactly the same as a V8-engined American-built four-door Dodge Dart Custom and had only slightly less power, but was taxed considerably less. These vehicles were also exported to other European markets such as France and the United Kingdom but without much success. The Spanish Dodges never met sales goals and was an expensive failure for the Barreiros concern. The break-even point was 5,000 cars per year, a goal which was only surpassed once, in 1966. The Barreiros brothers were forced to sell off the company which was reorganized as Chrysler España, S.A. The Dodge Dart GL was a luxury model, while the GT was the sporty version. The base version has a three-speed manual transmission, while the GT came with either a four-speed manual or a three-speed automatic - this was the same unit as the one mounted in the Chrysler 2 L. The gasoline Darts had the biggest engine ever mounted into a mass-produced car in Spain, the Chrysler slant-six engine. The "3700" number is a reference to the 3.7 litres of displacement. No other six-cylinder engine car has been produced as much in Spain. A diesel
