Well, the story of my Citroen experiences in France is basically this:
When we were looking to move over, we made a trip over in Summer 2000. At one point we visited a small market in Laroque-Timbault, close to where we were thinking of settling and I saw a photo of an orange GSX with a phone number. I took the number down and sort of left it at that, until, in 2001 we moved to France and I fancied a second car (at the time our Mercedes 300SE was a bit OTT for where we were). So eventually I got to buy it - for €400 - but it wasn't in totally brilliant condition, having been stood under a tree for 2 years. After two months, however - and a further €700 - it was sorted, a new CT (MOT), with all the welding done, a new exhaust, front discs (which were inboard I found out!) and skinny Firestone tyres. We also had rear seat belts fitted.The hydraulics and electrics were absolutely fine. Liz and I worked hard on the cleaning and cosmetics - it took two days to carefully scrape off the tree sap - using two pieces of thin aluminium which were soft enough not to scratch the paintwork. I drove it around for about a month before I took it in to the local Citroen specialist (who was a real gent) for a service and new spheres on the rear. I drove it home and spent the evening hand sewing a new leather steering wheel cover on!
The next day was Christmas Eve and we set off in the GSX 20kms up the road to a Christmas market, but never made it. Travelling along a deserted N21 I saw two cars waiting to cross our carriageway but seeing as they were just sitting there I thought they'd wait. Instinctively I did slow down though. Just as well as the Fiat Uno waited until just the last second before lurching out of the side road into my path. I would have missed her but she saw me and slammed on the brakes. I hit her front wheel at about 30 kph...
So the GSX was a write off.
On reflection I wish I'd bought the black vinyl sports interior off the scrappy as it was sooo cool!
Here's the GSX before that fateful day:
Three months later I spied a red Visa GTi on the roadside with an AV in the window and, well couldn't resist. I discovered the owner was a mechanic at the local Citroen garage. We had a test drive and I have to say it seemed very nicely set up - and a lot faster than I'd imagined... it soon became apparent why: he'd fitted a 30,000-mile 1.9 litre 8v BX GTi engine into it.
'Pig' - as we called her was a fantastic drive, (not so much fun for the passengers maybe) and the only problem I had was a bad gearbox leak. Took ages to fix, but got there in the end.
So what happened? Why haven't I still got 'Pig'? After all there was
no rust 
and the car was still red, not pink! Well we had to return to the UK in 2003 and I asked the local Citroen specialist I'd used before to find a buyer for it... He couldn't and time ran out so I offered it to him for not much (€300!!!). Still didn't want it (more a 2CV man he was), but he said he'd hold onto it until a buyer came along.
We returned to the UK but three months later 'Pig' still hadn't been sold, so I asked him to service the car, do a check-over and report back. It needed a new radiator - but that was it... So I arranged to fly over and pick it up.
To cut a long story short I went out, with my 10-year old daughter for a short break, We picked up the car (I paid him €100 for the work and rad - which wasn't bad!) and off we went. Agen to Calais (well over 600 miles) without a hitch, and then Dover to Chelmsford. This was the time of the run up to the Iraq war and the French were not exactly flavour of the month. No one believes me when I say we were nearly forced off the M25 twice by, let's say vans driven by big tatooed guys with short hair - once as we approached the tunnel we had to brake hard and swerve to avoid the wall!
At that point I really wished I hadn't come back to this country.
Anyway, the Visa was later sold on eBay for €800 to a Belgian enthusiast, so it might still be around somewhere!
Two months later we bought DGK - our fine GTi auto, which stayed with us for over four years and kick-started the whole BX thing for us!
