I should mention that I live out in the country in a town of 5500 people and its almost totally flat. In my 335i I average 26.4 with a lot of mods and a lot of spirited driving. I really dont ever goto seattle which is 2 hours away.
So I was hoping the m5 could average 16 mpg. I DD my duramax half of the week and its lifted on 38s and it gets around 15 mpg out here
Im looking at a white 08 M5 With red interior 23k miles for 43k with 6 months left on warranty
Or a black 07 with red interior with 60k miles for 35k im leaning towards the white one due to miles. And they are both 6speed manuals. No smg for me. I do plan on keeping the 335i for fun
