I found a better picture on-line.

It is clearer - the tail-lights are the hard part to distinguish. From this angle, it looks like the trunk is elongated, true. My Crickets had a transition point when looking from this angle. From the side, the change appeared to be minimal. Except for the chrome appearing 'B' pillar, the rest of the lines and there appears the be the vent in the 'C' pillar just like the Cricket.

I wish there is a front-shot. That would make or break this guess.
