THAT Saab 9-3 from the carpark out the back

This car caused plenty of conjecture when I showed it yesterday.
Fortunately the original photo was much larger than the one I posted, so I’ve been able to isolate a close-up of the car so you can see the details.
Here’s a standard 9-3 rear section for comparison…..
And a close up of the rear wheels.
I don’t know what’s going on with it. Much bigger rear wheel arches by the look of things, though I’m not sure why.
It might be one of the tech guys having some fun for all we know, but it’s good to get glimpse at these things.
