Thanks Tim, I have done 1800 miles in this car since late July2005. Is this too late to ask for a refund? I do like the car but I'm not prepared to listen to these intermittent knocks, whistles and squeaks and everyone knows that the hardest faults to fix are intermittent one's. I don't have a lot of confidence in my dealer and I'm already prepared for the excuses they're going to give me when they can't replicate the problems. Today I drove for 15 miles before any knocking or creaking occured! I live on an estate where there are speed bumps and what I've read recently has really put me off. The c3 seems to have a bad reputation when it comes to suspension problems. If I was to keep this car, I think in the end I would be on first name terms with everyone in the dealership. I don't want to name and shame them at this moment in time but they're on Merseyside. It's going in tomorrow - no loan car available because they need 2 and half weeks notice for that but they have offered me a lift home which is something I suppose. I think I'll write a letter tonight giving them 14 days to identify the source of the squeaks, creaks and knocks and to repair them to a standard whereby it won't happen again otherwise I want a refund. They've already had it in 12 days on one previous occasion. Cheers Peter (seat cover problem updated on my site)
