Good evening. Just joined as I'm probably about to buy a C4. Took a test drive in one yesterday, 16 month old 12k mils on, was an Avis rental but being sold by a Citroen dealer who say it is fine. Car drove ok, a bit noisey on hard acceleration, and box a bit clunky. I am a tad bothered about it being a rental car as it will have been driven by all and sundry, but it looks ok. Should I have concerns, or am I worrying too much. I will be using it to tow a caravan also Thanks.
