Sorry, still looks nothing like it!
Lamps are still different, DTM car has fat side skirts, flared arches and winglets on the bumpers, R9 body has none of these, windowline from the side is different, etc.
As I said though, I don't mind original design shells, but let's save ourselves from the pretence that they are based on reality!
Here is Tamiya's A4 DTM by the way...
And that Protoform R9 - sorry, "Audi DTM" according to EFRA...
