Maseriti Mistral by Frua

Emblematic of a new styling trend that lasted for 30 or so years was the BMW 1500, first shown in 1961.  This was for cars to have relatively short lower bodies and tall passenger compartment greenhouses.  That BMW was also a classic, squared-off "three box" design.

Not all tall-greenhouse designs were boxy, however.  A comparatively sleek example was the 1963-1970 Maserati Mistral designed by Pietro Frua.  Around 950 were built.

The seems to be a photo of an early Mistral.  Its main recognition feature is the extension of the frontal metal fold that continues under the headlights and then sweeps along the side as a character line up over the front wheel well and then dissipates just forward to the front door cutline.  That, combined with the wraparound front bumper suggests a mustache.

The low-volume Spyder alternative, again in what appears to be a factory photo.

Another possible fairly early image.  This car has an air vent in the form of a flap on the side of the fender.  Its hood is long in part because the motor is a straight-six.

Side view of a 1969 Mistral via Bonhams auctions.  The greenhouse comprises nearly 40 percent of the total body height.  This proportion seems excessive to me.  Also, all that glass is heavy, and driver views out the sides in most instances don't require so much glass height.

Rear quarter view of the same car.  The rear hatch/window is also large and heavy.

1966 "for sale" Mistral with no fender air vent flap.

Same car, showing rear end details.  Clean, simple, but don't those tail lights seem small by today's standards?
