Absolutely no major faults with this car, we haven't even had to replace a bulb yet. Minor problems include rear ashtray broken (after the kids stood on it) and the plastic surround for the cigarette lighter has come off due to the cheap plastic clips breaking. The drivers side window (on the left in France) sometimes stops about 2mm short of fully closed, and takes a couple of attempts to get rid of the resulting annoying wind noise on motorways.
The air conditioning didn't work too well, but investigation showed it to be the pollen filter (which I didn't know it had). Replacement part costs 15 euros, and fitted easily in under 20 minutes.
As part of general maintenance, I had the belts for the air conditioning, alternator, diesel pump and power steering at the same time as the timing belt and tensioners/pullys. The total for parts in France was 220 euros and labour costs took this to the reasonable total of 420 euros.
I had an Audi A6 2.5Tdi estate before moving to France, and had to downgrade to the Mondeo. Having said that, the Mondeo has been no problem to adjust to. Initially, the low-down power is very sluggish, and you have to keep the rev range above 2000RPM to keep the turbo spinning. If it drops below this, especially on a steep hill, the car almost grinds to a halt. Once you're used to this, it isn't a problem. The car is very economical for it's size, easily covering 700Kms on one tankful of diesel. It's very roomy inside, and the seats are very comfortable. We've driven a few times between Nice and Calais, a distance of over 1300Kms (800 miles) in 12 hours and I swear it's THE comfiest car I've driven, with no backache or anything after a day behind the wheel. As well as a roomy cabin, the loadspace in the estate version is nothing short of spectacular. Now it's 5 years old and not as cared for, we carry all sorts of gubbins in the back, ranging from dishwashers to my wife's excessive IKEA shoploads. The Mondeo swallows all of it with ease...
The engine only produces 90BHP, so it is good on tyres. Fronts have lasted 60000kms and rears half as much again. Most of that is country road driving with occasional very long motorway trips.
The Ford stereo CD6000 is a great sound system, and can be controlled from the steering wheel. An optional CD changer is available.
