Well I feel like I can tell my opinion aswell as I've owned both. I will say that the auto 5 speed box is waaaaay smoother than the 7 speed. As
freemansteve said, both are very different but I don't agree with one thing (Sorry
freemansteve :mrgreen

Quote: "and if a tad better MPG is crucial for an owner, stick with a 2.5".
I could avarage 29mpg with my 2.5dci and i'm currently 27mpg with my 3.0dci v6. So yes, the 2.5dci will always get a little bit better mpg, but let's get real here, it's not like 30mpg is "economical" :lol:
So if you are worried about mpg, this might not be the type of vehicle for you (although it's still your choice!) :awesomework
So why should you buy a V6, what do you get, that even a fully loaded 2.5dci can't? Well for once, it comes fully loaded (sounds stupid, but second hand you don't have to worry about it), Bose surround system (I like it a lot), v6 badges (to show off ofcourse, why else?), 7 speed not so smoos gearbox (but it can handle the mighty torque) and oh yes, the V9x engine which is awesome except at the petrol station.
If you need a worktruck and don't want to spend that much, go for the 2.5dci. You'll get a fine working truck, a tad better mpg, more money in your pocket and with a remap it will also go fast enough!
If you really want a v6, trust me and wait. I did too, and I bet some of the other members did too! Take your time, and try to get some discount. Either way, good luck with the hunting!
