I have to agree w/ jinstall. Not that the CRD isn't having some teething problems, we all should have expected that - I did. I think Jeep did a smart thing by offering the longer warranty for the first year. That along w/ the employee pricing made me go for the '05 instead of an '06.
But it really comes down to maintenance. My Dad was anal about his cars and has passed that on to me. He currently has 278k miles on his 1980 BMW 733i and 194k miles on his '91 Chevy pickup. You just have to do things a lot of people don't do - also I think doing your own iol changes and such allows you to spot potential problems before they leave you on the side of the road like worn belts, oil, diff, or xmission leaks, etc.
Now all of this to say that as cars become increasingly computerized, you can do everything right and sometimes some sensor somwhere just goes South and leaves you stranded. Sure it sucks but cars today are WAY more reliable than they were 50 years ago. Same for motorcycles - my Dad used to tell me stories of fixing chains and replacing points by the side of the road. That just doesn't interest me in the slightest.
The fact that we're on this board means that we're more interested in the KJ than most people - I'm looking forward to the day when we of the mechanically inclined will be able to have a nice computerized interface into the car where it could tell us of approaching problems, not after they happen and also allow us to clear codes and potentially override bad sensors, etc. I'm young enough to be glad that I can tune my motorcycle w/ a laptop instead of swapping carb needles and changing jets.
Got off on a bit of a tangent there but my point is that it's almost impossible to buy a bad car these days but if you want a car that you take to Jiffy Lube and otherwise don't touch it for 100k - go buy a Civic. I bought the CRD because it's new and complicated. I've never owned a diesel before so it's been fun installing a provent and such and I'm looking forward to a new muffler and other things. Yes, my KJ hasn't ever left me stranded so that could change my opinion. Since finding this board I installed a provent at 2k miles and so far (6k miles) no EGR. My only problem is the tranny shudder and I need to crawl under the Jeep to make sure my tranny # fits the TSB but it's been raining a lot lately and don't want to get wet
So have fun w/ it.
