Had a crazy idea:
As the Audi tt mk2 (2006) has the same wheel base as the corrado VR6 (93-96)...
Has anyone ever considered a body swap of a corrado body and interior to a tt donor chassis and drivetrain? Yes, there would be some frame modification to fit doors and roof, but you'd have an AWD conversion without having to trouble shoot electronics, transmission, engine and drivetrain retrofits.
