Picked up our 100D today: We both love it! The differences with the 75 are interesting - you can tell the difference between rear and four wheel drive right away. Not sure I actually like the D "feel" better as it seems to have a bit of torque steer, but I do like the extra acceleration. Maybe I just need to get used to it. I'm looking forward to the drive home tomorrow to see what else is different from the 75.
