I look forward to hearing more about it as you get used to it. I really wanted the diesel when they were announced. All else being equal, I think I'd still prefer it. But I can't see paying more than $35K
Around here, diesel is about the same price as regular, but Costco doesn't sell diesel

I get about 24 MPG on my 18 2.5NA on my regular communte. 30-32 on all highway trips in the 60-80mph speed range.
If I could average 30 MPG instead of 24, that meets my minimum expectation for the diesel, and if it does 35 on the freeway, that would be fine too. I expect it to feel much nicer getting up to speed from a stop, and not worrying about the gear, that's about my only complaint on the 2.5NA. I'd also like the improved towing capacity. And maybe the engine does feel more refined than the 2.5T. I wasn't blown away by that.
I'm surprised you didn't try the 2.5T. How did you know its the diesel you wanted at that premium?
