A great project - this 180B coupe seems to be a relatively rust free car, with a new paint job (other than under the hood), and would make a great base for a project. The car has been stripped inside, and has been modified with a 5-speed Nissan Bluebird gear box, and a Locked R180 diff. The seller's description is very limited, so we can only make assumptions based on what we have in the images. Potentially, the original interior may come with the car, as the seller mentions it comes with "many other things".
This one was advertised on Ebay Australia in March 2017, with an asking price of $10,000 (AUD).
