The C5 wont be to everyones taste, which for me is an advantage, it is well equiped with a rubish cup holder. I have done 60k in mine and understand its little foibles. The depollution warning will put it in limp mode, just restart it and it will be back to full power, it is caused by the DPF which needs cleaning, thrash it for a few miles and it will clean it and then the warning light will go out (use the gearbox to keep the revs over 3000)Tyres can be expensive but are good quality, brake pads last 30k on mine and the rear ones are a pig to change. The seat is extremly adjustable and as a six footer I have no issues getting comfortable, I do a lot of high speed motorway driving and get 40mpg with an auto box. I have had it back under warranty for a new fuse box, caused gearbox selection issues, a recall on the trim at the side of the windscreen and a short wiring harness on the brake pedal switch. None of these took more than 4 hours and the dealer is excellent. In summary faults are the cup holder and the depolution system. Advantages are a high spec car at a sensible price which I can do 500 miles in and get out without aches and pains. Would I buy it again? Yes and that is not something I have said about SAAB, Vauxhall, BMW, Mercedes, Pugeot, Ford and numerous now defunct brands of car.
