Sprinter is a great tow vehicle, my 02 cdi does 35mpg round the doors.Plastics for performance did the perspex set. Decent quality, and they curved the back screen properly. Must get the rally car to a weighbridge, so I know where we are. Look on the top of the accelerator pedal and on the rear of the gearshift mount. Two lumps of 'ballast' steel that you can live without.
