Solved - NEH 404: OTAS KL112 by Aldo Sessano (1970)

[Carnut]

perhaps if he'd learned to draw curves he might have had a bit more success...

I'm sorry to object. That's of course not the reason! The main reason is he never was closely related to any of the big makes or coachbuilding companies. He made many successful designs for Japanese clients, but Sessano's name was rarely mentioned on those projects.

About the rear view of the 112KL: I love it like it is! To me it's absolutely not nondescript, but pure and graphic. There's not always a big butt needed!

I was joking Allemano.  I know that wasn't the reason...  Just making reference to the fact that all the Sessano designs I know are very angular.

I didn't say it needed a big butt, just something more than a rectangular flat panel with cutouts. The back of the car has no connection with the design of the front - again, like the Gremlin.

Here's a better picture showing that rear end.
I rather like it myself..
