Despite the power boost, this engine quickly became known for its unreliability and production was ended in 1960 as a result. Still, this so-called improved engine allowed the small roadster to achieve a top speed of 113 mph and even came with Jaguar
racing style steel wheels. The MGA continued on through 1962 receiving regular upgrades along the way. 1961 saw the introduction of the Mark II MGA that attempted to correct many of the mechanical mishaps of its predecessors. By this time, however, the MGA was getting to be out of date compared to other British-made roadsters of the time, which included the latest version of Triumph’s TR series.
