My 2008 4.8i was much better than my 2007 3.0si. With that being said, my 4.8i was a nuisance. Transmission was the worst of any car, any brand any model I have ever had. It was rough, would hold gears to absurd and high rpms & then abruptly shift and just felt like crap. Tons of error messages, constant battery warning messages, iDrive screen would freeze, date and time was constantly erasing, satellite/radio presets were always erasing, or even changing (on their own!!). HVAC was dismal...always too cold, too hot and too weak.

I'm honestly very happy there are E70 4.8i owners who have had & are having a good experience with theirs, but mine was dreadful.

Also, I think we all need to be concerned with gas mileage. In the city, I always got 8-10 mpg in my 4.8i. So, when gas was almost $5/gallon (which it will be again..the USA cannot keep having such low prices compared to most of the world), it would cost me $10 to pick my son up from school and $5 just to go to the grocery store if we needed something. Very sad!
