Well I have passed the 48k mile mark in my 2010 C5 Tourer 3.0 HDI and thought I'd update you all on a few things, all good by the way
Build quality is still top notch, no rattles or annoying noises, well pleased with this and betters anything I've had from VW Group, BMW, Volvo and Mercedes.
Reliability, still very good, 1 recall and only service items to report, long may this continue albeit being a car that's used a lot, this may change. Might have to extend the warranty next March
Drive, other than the road noise created by the huge 19 inch alloys, the car, especially on motorways, is proving very quiet indeed, sometimes wonder if the engine is running at all
Although a big car, it does handle really well. I've had 2 VW GTI's and a VW R36 all very well balanced and capable cars and I have to say this C5 Tourer is proving it can cover ground as well, especially on the Bournemouth to Bristol route I frequent. Not too much body roll at all and the grip is exceptional 
The car rides very comfortably and can firm up nicely if needed.Performance, well I had the car remapped now for over 15k miles and have to say it does not disappoint. 300 bhp and 462 flbt it does shift, nuff said
MPG: I only ever bother doing proper brim to brim tests with mpg and again, I am very pleased here, especially noting the performance on offer. I recently took a trip up to Norwich from Bournemouth, unfortunately it was bumper to bumper on the way up and quiet on the way down, however the car still achieved an average of 45.2 mpg
I have had a lot of fun in the car and even when driving very spirited, I can still achieve 37 mpg. I must admit, I do more days when I travel sedately and my average is more around 40 mpg.The paintwork is holding up well although I do take care of my cars so this might be down to my hard graft polishing etc
I do though have the usual array of stone chips and might have to get some sort of protection on the bonnet if I keep the car past the 3 year point. Interior is holding up very well and looks like new still, even with 3 kids climbing all over it 
I have 3 kids and the misses and they all concur with the comments around comfort and performance, the kids love the huge sky roof.
All in all, well done to Citroen for 48k trouble free miles, long may this continue.
