I would go for the Sprinter

Quality van IMO......Owned a LWB one for 3 years, it was the 312 model - flying machine

Spec read like a proper performance car :
6 Cylinder 2.9, TURBO intercooled, RWD, traction control, ABS......would show 115-120 MPH on slight downhill sections - no problem

Was a very quick van, good brakes too, sold it to Steve Scott (A1 Rally Sport), think he still ownes it now

Paul Bailey has the same spec engine but in a SWB model - tweaked a bit too
