I have a 1983 505, maroon in colour, 5 speed manual (with a BA7 gearbox).
It has a fair few kilometres on it, but is still going strong. Tyres are old, but still roadworthy. For a safety certificate, it needs a little welding, and probably a couple of minor things. Body looks good, and apart from the bit that needs welding,(underneath the battery carrier) is relatively rust-free. Paint ok. Interior average. A good workhorse. Selling unregistered.....$500
