Cutting compound the body work and it will bring the colour back a treat, probably treat it to some nice deep dish wheels and just debadge it?

looks nice! panels all look good, a good t-cut will bring it up nicely!
Wow, You still have it! Hows she going?
Possibly an ignition switch fault? There are three different types fitted to Unos so a replacement will have to come from another Mk1 Uno 45. You could try cleaning it, but it is possible for it to be worn out.
There is a main electrical connection (in-line plug/socket) near the battery - separate and clean this and make sure it's tight.
