Faults:

Exhaust pipes leak - a bit of welding and the problem was solved (though it wasn't pleasant driving with that terrible odour until I found the leak)

One of the hydraulic return pipes broke, most likely during my 200km long trip home - however I didn't notice it until next morning (i.e. I got home safe) as it bled the car dry leaving it in a puddle of LHM.

Fuel line was poorly fitted - it was rubbing against front discs that eventually cut it in half. Not the car's fault, though.

All of this happened within the first month after I got the car and mainly because I never got around to checking it properly.

Standard oil leaks, not critical yet - to be dealt with this summer.

General Comments:

This is my 3rd GS - before I had a '78 Pallas and a '78 GSX. Those I sold out of pure boredom. The trick is to find a good one - rust being the main point here, also without any noises from camshafts (they tend to wear rapidly if a car is neglected, which is often the case). Parts and repairs are cheap, a good mechanic (a Citroen enthusiast) is the main factor in the car's reliability and running cost. The ride quality, handling and brakes are far better than in most moderns. It looks really cool both inside and out, doesn't use that much fuel (if set up right), drives surprisingly smoothly for a 1.2cc 30 year old car (just think of the sluggish VW beetle) and above all - is fun to drive. I went through quite a lot of very different cars from Renault a 4 to an Alfa Giulietta and a 2002 Peugeot 406 but the GS has an unmatched coolness/reliability/price ratio.

Faults:

The main problem with these cars now is rust. Mine has rusted on the under-tray.

The exhaust leaks and there are a lot of complex pipes in the exhaust system.

General Comments:

The GS has the smoothest ride quality I have ever experienced and yet the handling is superb with well weighted steering and a feeling of solidity and safety at speed.

The UK cars have a lovely sporty aluminum effect round dial dash.

Although performance is good for a 1.2 car it uses more fuel that most 2 litre cars if you drive it hard.

The engine is a flat four air cooled overhead camshaft unit so was amazingly smooth and turbine like for its time. This means that you don't get any of the nasty low pitch roar that you get from a normal engine.
