Can you identify this car?

Something to distract your attention and help pass the time…..
There’s a guy over at Saab Central trying to find out what this car is:
It looks a bit like a Saab Quantum racer, which were designed and made in the USA using bits of the Saab 96 back in the early-mid 1960’s. There were 5 styles of Quantum designed over time, with the Quantum IV being the most popular, designed with the idea of racing in a SCCA Formula S series.
This car has a somewhat different rear, however, hence the mystery.
Anyone got any ideas? If you have, the Saab Central thread is here.
My guess is a re-bodied Saab Quantum.
And whilst we’re talking Quantums, there’s one for sale in Wisconsin for $45K
