As said above, I tried to use ingo's terminology. But I'm not sure that the Gallic poetry could ever equal the Teutonic one


Infos I found are contradictory about the basis. When indicated, most sites say GS Club, but none agree on the engine: 1220 cm³ and 60 hp of the Club here (fr), 1220 cm³ without engine power here (fr), 1299 cm³ and 65 hp in the link I gave in the previous comment. This latter site claims several trustworthy sources, but that would mean that the Basalte would have had the engine of the X3 some months before the latter was unveiled.
An X2 engine would be a 1220 cm³ with 64 hp, in 1978 (since the 1976 MY, in fact - fr), but I didn't find any corporate document about the technical specs of the Basalte. The French ad says "7 CV" (tax horsepower), which doesn't help as both engines belong to that administrative category, whatever the real engine power they provide...


Citroenet.org.uk shows both French and German ads: 1,500 cars were send to Germany, but nothing is said about UK sales. 3,200 cars were made for export, so somewhere between a dozen to 1,700?
