They had a brand new 3.0 SC. It was "ok" I did not push it as much but handled pretty well taking off ramps, etc. It is better gas/miles than the 4.8i (23 MPG/ Hwy).

They had an 07 4.2 with only 35k miles just traded in but was not ready for test drive. I asked how was in comparison to the 3.0 SC but he said almost same.

I might go back to test drive with wife this weekend (when its ready for show). Not sure as wife loves the X5 and says the Q7 looks like a bus
