Please help! I've read and read these forums, looking for users opinions regarding the 3.0 versus the 4.4. It appears everyone on here favors the 4.4. I need to make this decision by saturday, and was hoping i could get some opinions and guidance. These are the two vehicles that I have to choose from:

CPO '06 X5 3.0 Toledo Blue/gray interior with 22k miles
Sport Package
Premium
Cold Weather (no heated wheel)
Nav
PDC
DSP Sound
$27K

CPO '06 X5 4.4 Sterling Gray/black interior with 33k miles
Premium
Cold Weather (with heated wheel)
Nav
PDC
$30K

I love the toledo/gray leather and sport package on the 3.0, but thinking i may be happier with the V8...im coming from a 335i monaco/saddle brown. The twin turbo power is nice, but definitely find myself driving maybe to aggressively because of the power.

What would you guys choose?
