hi there
we have the Exclusive version with the 2.0hdi semi automatic gearbox. The towing max is 1500kg, the early brochures state 1300kg which is a typo - Citroen will confirm in writing it is 1500kg if you ask (which we did). Train weight is 3600kg, car weighs about 1620kg depending on what extras you have. We tow an Abbey weighing in at 1490 MTPLM. it tows it absolutely fine and we average about 27mpg. I have towed in both manual and auto mode, I get a slightly better mpg in auto and it isnt bad at working out the correct gear apart from hills when you need to change down before the car wants to.
It's a great car, but personally I dont like the gearbox that much (it's the wife's car!). We have had the software upgraded as it was very jerky when changing gears and it is much better now. We have had problems reversing it on site, but that was human error by not moving the 'van forwards first then reversing (we're new to caravanning). It also has got stuck in a very soft field, but to be honest, any front wheel drive car would have.
Overall its a good car, very stable when towing and the auto levelling suspension is excellent. I would recommend it, however this is the first and only car I have towed with.
if you want any more info, let me know
cheers
Brian
