Dawson, I've been struggling with this choice as well (V10 vs PSD). Tried to do some long term math: how long am I going to keep it, how many miles, how do I drive them, guess at the the fuel economy (I don't think any one of us drives exactly like the others here), and what I think the difference in price between gas and deisel will be while I own it.

My theory at the momement is that the difference is small enough that I should get what I want. Now, if I could just figure out what that was...
