I have an Exclusive 1.4HDI 16V (53 plate) which I haggled £1800 off plus the full-size sunroof thrown in which was £500. Reason was there were no red ones so I took a silver one as they did not want to lose the sale. Anyway, on a trip to London and back (500 miles) it averaged 68.9mpg for the round trip with four of us plus luggage. It now has 26k on it and overall does 61mpg to and from work and round town. It does not have lumbar support, but does have climate and cruise control. The only problem I've had was a broken window switch which was replaced under warranty. If you do decide to buy one, be very careful of the dealer you choose as they can be diabolical (Dixons - Bradford) or alternatively...excellent. It handles well and never goes below 50mpg and the servicing which has to be dealer is £155 a go or cheaper if you can find a CITROEN APPROVED dealer. Personally, go on EBAY and buy one there, unless you are certain the dealer gives a damn!!!
