SH Arnolt Inc. of Chicago and Warsaw Indiana sold four different manufacturer's cars with Bertone bodies during the period 1953 to 1968. 

The first was the Arnolt-MG, a four seater Bertone bodied car based on the MG TD chassis and XPAG 54hp engine. The Arnolt MG was designed by Giovanni Bertone, his son Nuccio, and Giovanni Michelotti. Of a planned production of 200 cars, 103 have been documented as built between 1953 and 1954 (67 coupes and 36 convertibles). Out of this total, the whereabouts of 36 are unknown and three are known to have been scrapped (as of 1993).

The initial price was $3145. In 1954, MG informed Arnolt that it could no longer supply chassis and engines due to demand for its own complete cars (as well as the replacement of the TD by the TF), so Arnolt began looking for a larger engined car.
