I would say whatever is wrong with it it will be fixable! Not like when "the Computa" goes kaput for your modern cars, and despite all the diagnostics available, many threads will testify that in general, the main dealer is just as clueless as the rest of us.
Peugeot 204? Can't decode French Number Plates to get the year. Somewhere between 1965 and 1976 but more likely to be 70's.
