FWIW, I ran the numbers on the Grand Cherokee, and for the premium cost of the diesel engine you would have to drive over 100k miles to make up the difference in mpg cost savings... So don't get it thinking you are saving money. If you want the torque or pulling power, or maybe the piece of mind that comes with knowing you could burn bio-diesel sometime down the road, fine. But having an X now is worth so much more.

I did too. It claimed I would save around $20 a year in fuel costs, and a total of 7 minutes a year at the pumps refilling.
Then the website challenged to dream of what I could do with that extra $20 and 7 minutes.
Resale on a Wrangler is pretty good. Buy now and upgrade later.
Let the diesel come to market and see how it works out. In a couple years, if you HAVE to get one, you'll have a vehicle with great resale value and you'll have had a lot of great times in the rubi while you waited.
When the diesel comes out I will be ready to buy one after two years of production. My justification is that the quirks needs to be worked out even if they use the same diesel as the GC. SO that is what 4-5 years? No way buy now be happy now and later!!
Let's see, gas here in western PA $3.57/Gallon, diesel $4.55/Gallon. Nope, I wouldn't wait. No way I'd ever make up that kind of difference. Besides I'm waiting right now for my new Rubicon X to arrive.
Like others said dont do it thinking you will save money.
Considered trading my Ram in on one of the new 1/2 ton Diesels but after doing the math it would of taken 4 years to offset the costs.
I have only owned one vehicle in my life for 4 years so most likely would of never seen a savings.
Plus the added inconvenience of the station I get gas at doesnt sale diesel.
The only thing I think you aren't taking account of is the resale value. The resale value of a diesel engine(as long as it isn't a lemon) is going to be a lot higher than the gas engine mile for mile. When you figure in the resale value I don't think you would be out that much more money.
I love diesel engines in the trucks I have owned. I'm just not sure I would want one in a Jeep Wrangler.
