a patchwork heart...: which one?

we are lookng at buying a new (old) van.. we want diesel so we can run it on biodiesel/veggie oil..our choices have been narrowed down to a toyota and a mitsubishi .. they are similar in most regards (both 91', have 7 or 8 seats, diesel, right hand drive, very low mileage and they have skylights!!!...) the mitsubishi is a 4X4 with a truck chasie and is said to be very reliable and well made. the toyota has seats that swivel and fold up in all sorts of ways and is also said to be a great family car... there is about $2000 difference between the two.
im partial to the toyota, timothy to the mitsubishi..how do we decide? money is an issue, but we want to make a good choice as it will probably be our car for the next 10 years. timothy even did a tarot card reading last night.. it said that the toyota is the more practical choice but he still wants to get he bigger fancier one.. okay yes..it has a cooler box that makes ice or heats things up and has a pushbar and winch..it is a very manly van. but, it costs a lot more and it is pretty much the same van..how often will be be going off roading in our family car? well, not that often..
the biggest thing for me is that the toyota is a lot better on gas mileage and until we convert the engine to veggie oil it is still going to be quite expensive to drive - as biodiesel is still around $1.oo~ a liter -
this is what they look like.. the delica we are thinking on is all white with skylights (crystal high roof).. the toyta is the one that we looked at a few days ago..
