The 912E is one of the best Porsches Porsche ever made. A great cruiser and a pretty good auto-x car also.
I've owned one since new - it is now carbed since the FI went away.
When it was new I could drive it 90mph and get 35mpg, at present it gets 25mpg.
With a 21 gal fuel tank, one needs to find a comfort station before needing a fillup.
Porsche only made 2099 912E's in 1976 and only 500 were built with a sunroof.
I've owned 3 and still own 2.
A great daily driver.
