Hello all my name is zac, I am new to the KJ forum although I have owned my Jeep KJ 2.4 CRD 2002 for a few years now and have been spending ALOTT of money on this car. I really enjoy driving this car although it is costing me an arm n a leg to keep it driving. I'm just wondering if the hefty maintenance will eventually pay off? or is it worth cutting my losses as I ideally want a car that is reliable. I've replaced the clutch and majority of the suspension and now I need to replace timing kit (timing belt, idler pulleys, tensioner pullies, tensioner) which will cost me around AU$2,500 to repair which at the current moment I cant afford.
