Siam Di Tella. (1960-67)

B Series 4-door saloon & Pick up

The Siam Di Tella was launched in 1960 in Argentina. What is it doing here? you may ask, well the simple answer is that in many ways one of the models launched was essentially a Riley 4/68. The suspension was stiffened to cope with the local roads, and the compression ratio reduced to cope with the local fuel. This also meant that the maximum bhp figure dropped as low as 55! This also saw the top speed fall to about 70mph. The cars proved very popular as Taxis, a role which many were still performing 10 or 20 years later. There were also some rather unusual pick-up models, using the Austin/Morris Pick up body with a Riley nose.

In 1964, Di Tella neared collapse and so after re-organisation the company sought to cut costs. One of the ways seems to have been to stop badging the cars as Siam Di Tellas, and instead they were badged plain Riley. After the Riley version was launched, it was followed by a Siam Magnette (essentially the MG Magnette MkIV) with 1622cc engine, and then in 1964 when this model became a simple MG Magnette, there was also a Morris 1650 model sold.
