For some people a standard GS is just not enough. They like to convert they're cars to their individual taste. Over here you can see some examples of adjusted cars.
Ultra tuned Break
This GS Break is from Indonesia, looks like a very nice tuning job to me...
This GS diesel is a converted Birotor. The engine comes from a CX2500Diesel. A unique car because the GS never was available with a Diesel engine.
GSA Cottage Pickup
This GSA Pickup was spotted at a French Citroen dealer. The base for this pickup is a GSA Cottage Break. The roof has been removed, right after the B-style of the car.
This GS Break has extreme large wheels. Infact so large that the the rear wheelarches had to be adjusted to fit them
I found this image of a 4x4 GS somewhere on the internet. I have no further data on the car.
Citroën Bus with GS rearlights
I spotted this Citroën Bus at Citromobile. They used GS rearlights for it.
Citroën dealers also used GSs and GSA as Service cars. Often these where adjusted GS or GSA Services,, equiped with Citroën logo and some tools to help stranded motorists. Underneath a couple of pictures of such cars.
Above GSs have all GSA doors. Mostly this is done as the originally doors have severe rust damage. You can fit a GS door in a GSA and likewise. However the doorhandles are not replaceable. The car on the right however is a different story.
This is a GSA Break converted to a GS Break. You can only tell by the in this case original GSA doors and by looking at the dashboard, that is not replaced by a GS Dashboard.
