I have owned this car for twelve years. I purchased it from a Dentist that had restored the car in 1981.
It was a 911E Soft Rear Window Targa that he had converted to the fishbowl rear window you see.
I am in process of converting it back to the soft rear window.
The car was also converted from a Sportmatic to a five speed.
The front suspension is the 911S suspension.
