Maserati Mistral Spyder 3.7

Maserati Mistral Spyder

1964 to 1970

Already available in the coupé and in the Sebring, it became a somewhat less popular choice, when, in 1966 the new 4 litre unit was introduced. However, more than half of the Mistral Spyders assembled were produced with the 3.7 litre engine. A customer could specify an automatic gearbox on both the 3.7 and 4.0 litre versions.
