    Dont know what they are like to drive but standard is 177bhp. Get dtuk box and it goes to around 210-215 with 500nm of tourqe. mpg will be far better then a Vec B gsi upto double from what my V6 B did lol

    The Vectra B GSI and the Vectra C SRI 3.0 V6 CDTI are almost identical
    The only main difference is the old GSI returns about 20 to 25mpg, the 3.0 V6 CDTI returns about 30 to 35mpg
    It is for those reasons I chose this model

    Tuning the 3.0 V6 CDTI is not recommended

    I think people have successfully tuned the pre-face without any problems but dont tune the facelift.

    The Euro 3 version of the 3.0 V6 CDTi (177PS) responds well to a tuning box or re-map to around 210/220bhp.

    The Euro 4 version (184PS)does not like tuning in any way apart from your usual air box mods etc, with this some Euro 4 cars see near on 200bhp, as 184bhp is a little on the conservative side. But stay away from mapping and box's on the euro 4.

    It will be a different beast to the Vectra B petrol, the diesel has lots of low down torque but I would say, balls out performance would not be too different but the mid range overtaking clout of the V6 Diesel will be better.

    i drive both of these the vec b sri with lightened fly and 3.0 cams remus centre and the 3.0 cdti
    Vec b
    lots of fun responsive and 28 - 36 MPG (on trip).
    Vec c
    Comfortable, slowish in first and second comparde to the vec b. When its moving and the revs are above 1900 it flys. doing 32 -36 MPG as i am still enjoying the torque.

    HTH

    The VXR and V6 Diesel cannot really be compared

    Yes you can fit snowflakes, but remember to have XL load rated tyres for that extra bit of safety.
    Now I need a turbo to keep up!
