I bought this 06 750i on the last day of the month and got a great deal. car is certified. my only complaint is the around town gas mileage - is it me or do you get about 10-12 mpg in city driving on a tank. Freeway does much better. I have the two different size tire layout with 40s on back 45s on front. perhaps that contributes. Car is a rocket ship on the freeway I have also had trouble with passenger door lock - it sticks.
I drive once you get used to it is great. love the ability to shut down the battery/electrical power with the flip of switch to go away and leave the car "sleeping" on power.
Fuel economy. PS anythoughts on how to get better?
