Well, you may have answered your own question. The biggest reason *I* see to use diesel is for fuel economy. Let's see, i can get 15 miles @ 2.69 a gallon in my VX, or 45 miles @ 3.24 a gallon in my VW. You do the math. Would a conversion be worth it? I doubt it - I don't see how you are going to convert an ignition engine over to compression and get anywhere near the performance and efficiency of an engine that's doing what it was designed for. But an engine swap might work out nicely.
