It will also cost you more in 2014 and it will have a lower cost to operate. Most people who buy the TDI expect to keep them for a long time and/or use them for many miles.

Or... look at the Q7 S-line vs TDI Prestige
Look at the A3 too.

"The average used retail is the average price that this car, in excellent condition, has sold for at dealerships. This price may vary based on installed options, mileage and the cars overall condition."
Or, http://www.cargurus.com/Cars/2010-Audi-Q7-Price-c21917, select "refine price" and notice the TDI does command more.
KBB also has the same results, but their site is a PITA.

I would like to see better information about this.
I like diesels; have owned one in the past; was a good experience.
But:
- the cost of diesel fuel in both the Midwest & pacific northwest has been so high as to virtually negate any advantages of fuel economy.
- diesels (in the past) needed more frequent oil changes & had a greater number and higher priced filters that needed changing -- making routine maintenance higher than a gasoline engine
- the depreciation rate seemed little better than gasoline cars (yes, the resale was higher, but the percent depreciation seemed about the same)
- one might also suspect that the general expertise of U.S. mechanics favors gasoline engines (one would assume that Audi dealerships have had adequate training; don't know if it's just a few mechanics that have been trained on the TDI's or essentially, all of them).
I'm waiting to see if, over time, our fuel production and/or taxes aren't modified to favor diesel fuel (as they are in Europe--which drives much of the diesel enthusiasm there).
For now, while I might get a diesel just because I wanted one, the numbers are not that compelling. I'd say buy what you want -- but don't expect to necessarily make money by having paid more for a diesel.

Even the Diamond DA-42 uses Mercedes A-class diesel engines and it burns 12gph... for a twin engine, that's incredible. And Jet-A is cheaper than 100LL. We all know that diesel tax is higher because, well, it just is. There's "talk" about raising the gasoline tax because the last increase was in 1994 or something like that. I'm all for a gas tax raise if they don't increase diesel tax. That will only make diesels more valuable. But it's best not to speculate.
The only things to hold back someone from a diesel would be:
City driving - anything better than 35mph highway is worth buying, but if you're stuck in the city, just swallow your pride and get a hybrid.
Ice cold climate - winterized diesel is fine, but cold mornings and long engine warm-up times may not be your thing.
Lease junkie - you're not going to put on enough miles to see a benefit.
Waiting for an act of congress to increase/decrease fuel tax is way too political for me, but if you have the time to wait it out, then so be it.
While the TFSI supercharged V6 is a mighty fine engine, I would prefer the TDI for long-term (8+ years or +100k miles).
Unless you're going to keep a diesel past 120k miles, what's the need for a mechanic?
Just avoid prepaid maintenance, especially on the MB E250. Audi Care is roughly $900 but Mercedes dealers are actually charging $3500 for prepaid oil changes!!!
