Chassis assembly was relatively quick once everything was painted. Some minor fit issues were easily overcome.
The underside has decent detailing, although the exhaust pipe and transmission are molded in.
In the absence of a strip of fabric to go with the photo-etched hardware, the seat belts are strips of painted Tamiya tape.
The stance looks reasonable; the rear track seems a bit narrow, although this is consistent with period footage (click here). It was a short little thing, too, with quite a bit taken out of the wheelbase of the production quattro.
Body work is next, including approximately 20 photo-etched wire mesh screens. Seems there was a lot of heat to dump...
