My Navara is sitting outside the office just now if you want a look at something left field. It's big, not that quick off the line but once it's rolling (even 10mph) it goes very well.
Have a try of a couple of diesels, Q7s, MLs and V8 Rangie diesels all have bags of torque and are a nice drive.
I'd love the Cayenne Turbo, a phase two would be my pick of the 'quick' jeeps if it were my money. Nothing else compares in my opinion, not even close.
Have a look at Dunecht 4x4 (diesels) and Culter Car Centre (quicker luxury stuff) as they normally carry a selection.
