Just crunching some numbers between equivalent cars:

2006 E320
KBB $26,500
Fuel cost 3.98
Economy 27 combined
Cost for 1000 miles - $120.00

2006 E350
KBB $21,000
Fuel cost 3.67
Economy 20 combined
Cost for 1000 miles - $146.00

So, for the savings I would have buying the gas car, I would have to drive the CDI around 200,000 miles to make up the difference which I should have no problem doing.

Or, I could get a 2007 E350 with fewer miles for around the same cost as the 2006 CDI.

So, basically, it comes down to actual maintenance costs between the 2 cars and potential failure areas and costs.
Is the $3.67 Premium or Regular gasoline? Around here premium is nearly the same cost of diesel currently. Although gas prices fluctuate daily while diesel stays nearly constant.


However doing calculations based upon a few dollars in fuel savings that will take hundreds of thousands of miles to recoup the costs is irrelevant IMHO. Figure out which car you would prefer to own/drive (for reasons other than a marginal difference in fuel costs) and buy that one.
