Maserati GranTurismo MC Shift mpg

[Waitey]

Afternoon Gents,

I'm currently re looking into the world of buying the above, most likely to do around 12k p/a.

As part of my man maths speadsheet I have a costing for fuel as a part of it.

What MPG will a Granturismo give at a steady 70 on the motorway? Is it low 20's or will it creep into the mid 20's?

Thanks guys!
