Faults:

Drivers electric window switch broken on purchase.

Poor performance (cured by cleaning air mass meter).

General Comments:

Only had it 2 weeks, but really comfortable.

Doesn't like to be hustled round country lanes!

Getting close to 40mpg overall, which is OK considering the performance and weight of the car.

Lots of electrical toys, which all still work, bar driver's electric window switch, which is a common problem.

I've been in the trade for over 10 years, and C5s have a shocking reputation for reliability, which is deserved or undeserved, depending on the car you get. Seen these with over 200k on the clock never having given a problem, OR you get a complete nightmare that will drain your bank quicker than George Best on a quiet night out.

Switchgear is not as intuitive as a German car, and the quality of interior fittings only average.

Ride comfort is totally sublime. Only bettered by Jag or Merc.

The engine is very quiet, but doesn't have the urge or economy delivered by German units.

The cabin is generally well laid out.

Silly faults, which are typical of french cars are; door bins, which fall open when you close the door, and armrests that need to be lifted every time you put your seatbelt on.

Do not buy if you want a A4 or 3 series BMW. The C5 is a distinctly left leaning, Gallic vehicle.

By the way, a child could have penned a better looking vehicle.

Faults:

Upon buying the car, the fuel pump failed, so a new pump had to be fitted; cost 300 quid.

Drove the car home, and the gauge just dropped even though there's £50 in the tank? Any ideas on a quick fix without breaking the new seal to the pump? Have checked the electrics; no faults showing?

General Comments:

Nice car, and drives well.

Faults:

Electric windows had a mind of their own - just once.

Driver's door doesn't unlock with the remote.

Lacquer on the front bumper is peeling.

Radio doesn't store pre-set stations.

General Comments:

The things which have gone wrong are not faults at all, more observations to me...

Not the quickest in its class but it is very economical for its size, I'm averaging 50mpg plus.

The most comfortable ride I've ever had, and the most comfortable car I've ever driven: Did a trip from Glasgow to Bournemouth and didn't feel tired at the end of it!

Very soft handling, but then it isn't designed to be thrown into corners like a sports car - if that's what you want, get a low-slung sports car!

One problem with the ride... on twisty roads, passengers in the back have known to feel seasick (due to the way the Hydractive Suspension works). However motorway mile-munching it couldn't be better for passengers.

Faults:

Faulty suspension on 4 occasions.

Faulty Turbo charger.

Gearbox would not change into 4th.

Faulty air flow sensor.

Faulty wheel bearings.

Heater stopped working.

Instruments stopped working.

Central locking occasionally doesn't work.

Both headlights stopped working on one dark evening.

Air conditioning stopped working.

Service light comes on even though it doesn't need a service.

Airbag warning light illuminates all the time although it is always off when the car gets to the dealers.

General Comments:

This is my company car, which was bought for me when it had covered 15,000 miles.

I have to say it is the most unreliable car I have ever had. Barely a month passes without something going wrong with it.

It is also ugly, and is slow with lumbering handling and numb steering. It is also not comfortable due to the ape-like driving position.

I really cannot wait to get rid of this car. if I had bought it with my own money I would be very upset.

It has also cost several thousand pounds in running repairs to keep the car on the road due to the problems listed above.
