Fairly new Jeep owner - picked up a 2006 3.0 CRD last month mainly to tow my caravan.
Love this engine and the power is to be believed.
fitted built in Headrest screens with DVD players
Rear view camera
Side bars (it doesn't go off road as such so not bothered about clearance)
Chipped it - added about 30 bhp mainly to get it into top gear at lower speeds as wife uses it to do school run so low speed drives - improved mpg no end (and even more fun at the lights
