I've got a 2009 2.2 TDCi Titanium. I love it. It is plenty fast enough, handles well for such a big bus. It's now got 45k on the clock and i've not spend a bean on it over and above normal maintenance. Its been totally faultless. Its going in tomorrow for rear pads and discs (can't understand how the rears have worn before the fronts, but the fronts probably are not far off). Its OK on tyres. I got through the first set in about 15k miles but tracking was out, the current set are still going strong with about a years life left (so 10k miles-ish) after 30k miles. They are expensive though due to the weight rating - about £130 - £150 per corner for premium brands.
Its very comfy, has all the space you need, I can fit two big 29er AM bikes in the back on an internal racking system, so great for security if i'm leaving the car in a car park. The 6th and 7th seat are fine for kids, and for leggy adults might be a bit uncomfortable on a long journey as they are low to the floor so their knees are up by their ears - if you want the 6th and 7th seats for adults then go for the Galaxy.
I'm getting a consistent 40ish mpg - so thats about 550 miles per tank and I don't drive it particularly economically. On a long run i've had over 600 miles out of a tank and it probably could have squeezed another 20 miles or so out of it if i'd wanted to. It costs about £85 to brim.
With all the rear seats down you've got a totally flat floor and its cavernous. Brilliant for the tip run.
The middle rear seats slide fwd and back and recline, so are comfy for the occupants.
Its well built, very comfy, gobbles up the miles, attractive, is capable of putting a smile on your face when you're on your own (i'd love to strip out a 2.5T one as a track slag for the sheer hell of it), well specc'd. I really struggle to see anything else that i'd prefer to have - nothing else . I'm going to keep it for a few more years then get a big estate.
