If you look at the daytime pictures, there are loads parked on double yellows in exactly the same way.
The sort of guy who has an RS4, and Evo 6 Xtreme, a 205 and other cars, has over 9,000 posts on the MLR and is clearly well known is highly unlikely to arrange having his own car torched. or have financial difficulties. And honestly owning those cars is probably more likely to honestly sell them. He'd get more for the Xtreme sold than a pile of rubble, with the mods on it.
Maybe give the guy a break??
