I def. will but for my it will depends on the price fully, If it costs 10k more then a 3.5si for around the same power, how can I justify the gas savings when I keep it for 36mos, I would still be in the negative vs if I just sucked it up and paid for the gas, catch my drift?

Having heard all the good things about the diesel version of the X5 from drivers on this and other forums, I will definitely consider this version in my purchase options. What I don't know of course is the cost difference with the gas models or if there might also be a new gas model to choose from as well.

Assuming the diesel will cost more than the 3.0si model, the increased amount together with the driveability of that model will probably be the determing factor (all this assumes I can get my wife onboard to buy one in the first place!)

I've started to look around the gas stations in my immediate area to see how convenient it would be to get diesel fuel nearby. There is certainly some availability but not extensive as best I can see. The cost is, however, lower than the mid or premium grades of gas. That together with the significantly greater mpg for the diesel is a another compelling feature. Here's hoping...

P.S. Will the diesel model take the current grade of diesel fuel or does it require the new low-sulfur type? Is the low-sulfur type replacing the old stuff???

The new generation diesels everyone is making are all great engines. Depending on pricing, etc, a diesel would be high on my choice list for something like the X5. I've owned a couple of Dodge diesels, and those engines are incredible, the '05 in stock form would pull that 7200 lb truck past 60 mph in about 7.5 secs and still get 18-19 mpg on the highway, which is more than my X5 gets! 650 lb-ft of torque is wonderful thing!!
And the new diesels are quiet, don't smell and are easily upgradable to get even more power.

All diesels sold in the US from 2007 model year on are burning the low-sulfur diesel, so yes, the BMW diesels will be low-sulfur

It depends on the price differential and how much the model will benefit from it.

I would consider it, esp in the X3 model.

However, I would not be 1st or 1001st in line and
pay some Stlr markup jive for it. I would like the
torque and mpg...maybe a year after the heat
and dust dissipated?

I see you motoring around in a X3 3.0sd, 6-MT!

Yo M, me too...but I suspect the Biff&Buffy NA mkting brigade
will send the MT 6 packing any year now.

I still like the X6 looks alot! Hope they have something
with sport susp., IL 6 and under 60Gs with goodies, out the door.
Time is on my side, car buying-wise; life-wise, I'm in the
7th inning stretch and hoping for extra innings.

I would consider a diesel for certain types of vehicles, but would be unlikely to buy one for my next car, even with no price premium.

If I needed a pickup or truck, absolutely.

If I wanted a very fuel efficient 1 litre or under micro-car for city use, yes.

If I wanted a 2 to 3 litre sports sedan, absolutely not. Been there, done that, just had to give up too much IMO. The car loses the engine refinement that for me, is the reason I buy a BMW. Petty annoyances like no revs, lots of fumes when filling the tank, additional engine noise, even with the new models. I haven't driven a 2007 or 2008 BMW diesel model yet, but I have driven lots of Euro diesels in the past seven years. Torque is nice, but it isn't everything.
