That is a 504 GL that I picked up during Covid lockdown. It did not have an engine and had sat in a shed for 20 years. Very little rust so I cleaned it up, painted it, refurbished brakes, fitted a 2nd hand engine and registered it. I then bought a 505 GTI which I still have so I sold the beige 504. Since then I picked up 404 which I'm currently rebuilding. I need to update my garage photos. So I have the blue 504, a white 505 and the 404 pictured. How is you restoration going?
