I thought the Miata was ugly, until I saw a PT Cruiser. ;-)

The design is reminiscent of the Chrysler Airstream, which was
a major flop 70+ years ago.

AFAIK the Airstream was not a major flop. The Airflow was, but
mostly due to really bad manufacturing defects.

I might have gotten the name wrong, as I was in a rush. Regardless, Chrysler
produced a "streamlined" car that the public didn't warm to.
