People rarely do the actual math....
I can't believe people HERE are not doing the math.
So let's say gas is $3.50 a gallon for REGULAR, people see 70 cents a gallon more for diesel and go OMIGOD THAT'S SEVENTY CENTS MORE.
70 cents a gallon is 20 percent more.
My TDI wagon, based on a year of hand calc'ing gets 38 percent better mileage than the car it replaced, and that car was not a gas hog (Matrix XRS).
Here's another factor, draw up a list of "interesting and fun cars" - then check and see how many run premium....my Mazdaspeed Miata requires it, the wife's MINI Cooper (based not an S) requires it.
For the year I have owned my TDI, premium has been from 50 cents less than diesel to 20 cents more, right now they are priced comparably.
So AGAIN DO THE ACTUAL MATH before you freak out.
Now if you are soley buying a diesel just for the mileage, you have to figure out the amortization costs of the diesel version.
In the case of JSW's, comparing apples to apples, if you buy a SE gasser vs. a base TDI w/DSG (so both have autos), the cost difference is $2,780 more than a SE.
So depending on how much you drive it might take you 5 - 10 years to amortize that additional cost but that does not take into account crazy high TDI resale values so I bet it's 5 years or less.
Bottom line for me:
1. The economy is just part of the picture with a TDI, you have to like the way it drives, the extra range, etc.
2. Diesel is more expensive in this country due to extra taxes levied on the fact most diesel use is commercial trucks.
Some of the "coal pourer" redneck truck types like to blame low sulfur diesel but it only adds about 8 cents a gallon to the refining costs....
