I have an 2007 R320 and it's gets spectacular fuel mileage for a car it's size. I don't know much about the new diesel engines and what is required with the urea filters, etc. Diesel fuel is running on par with the cost of hightest gas. Diesel's last forever...

After 30-50mi test intervals on a long trip with my R320 CDI diesel here are my results:
55mph = 30.8mpg over 30 miles
60mph = 29.8mpg over 30mi
65mph = 28.2mpg over 30mi
70mph = 26.5mpg over 50mi
75mph = 24.8mpg over 30mi
entire trip was almost 900mi & 13.5hrs with an overall avg. of: 64mph = 28mpg (overall includes 4 bathroom/meal brakes, all other results above were non-stop 30-50mi test intervals)
FYI for comparison purposes I did some test drives before buying this car and with identical test drive routes i got 23.8mpg in a deisel R320 vs. 17mpg with unleaded gas R350. (about 29% better milage with diesel engine, yet in my area diesel is same price as Premium unleaded and diesel was about 10-12% higher than low grade unleaded. And diesels are "supposed" to last about twice as long as their unleaded counterparts. So, still better value eitherway with diesel.

Honest question, Im looking to buy a 2008 R350 or a Buick Enclave. Which do you think is the better buy. Im looking at mechanical, gas, performance and value.
