Z4 sDrive35i vs. Boxster Spyder vs. 370Z

Ok lemme start off by saying: The Z is in there just for the heck of it.

My initial impressions and predictions.

Z4: Engine sounds horrible IMO (Sorry BMW). Turn in feels a little slower than the others. Also feels the heaviest. Feels slow (could be because of engine sound)
Boxster: Feels like the lightest. Most fun to drive. Sharp turn in. Feels quick.
370Z: Feels in between the two Germans. Again, not slow but not fast either.

The track is the same as last time. From 1 Eagle Crest sign to the other.

Prediction

1st: Boxster
2nd: 370Z
3rd: Z4
-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Results:

Z4: 3:58.8 (wasn't completely clean, hit the sides of 2 traffic cars, so not a head on, but not clean)
Boxster: 3:57.9
370Z: 4:09.0

I have to say, the 370Z's times were a little unexpected...

Im going to have to give these a run as well.
