Double post!!! Screw it... It's my thread.
So what are my thoughts for the first day? Well, it is quick and nimble. It is certainly faster on the get go than the Cayman S, and likely has 90% of the handling. That might be because the rear tires are getting close to Corvette size at 275's. As a bonus, This car falls into BS in the Auto-x classing, down from the AS that the Cayman was. So it is certainly faster with much of the handling, but yet falls into a slightly more forgiving classing.
Now for the bad.
It has Nav, and on BMW's that's kind of a pain in the assay. Not as much as a couple years later, but still nowhere near where it should have been for the day given the competition at the time. This doesn't cover the fact that the Porsche was even worse on the infotainment, and I'm happy to have Bluetooth for the phone in Bianca.
Storage is at a premium in the Z4M. There is nothing of a glove box, and I can likely only keep a pack of chewing gum and some beef jerky in it. The beef jerky has to be shredded though, and the pack of gum half finished. In the Porsche there were pockets everywhere. Under the armrests in the doors, above the motor, centre console, and a large glove box. Bianca has a huge console compartment behind the right elbow, but half of it is taken up with a DVD player. I'll likely correct that.
The trunk fits what it needs to and that's about it. As a single guy with no kids... It holds what I need. Golf clubs and an overnight bag. I can likely double up this payload though with a careful amount of Jengasizing.
Lastly, I see a cone or two getting demolished as I can barely see the front corners of the car over the fenders. when I learn the car more, I'll get the feel for it, but it's not as easy a drive as the Cayman.
As for Wow factor.... I can say that today I have had more people compliment the car, and give thumbs up as driving, than I ever did in three months of owning Bernadette. Just on the way home alone, there was four thumbs up on Deerfoot from southland drive to Stoney south alone. You just don't see these cars on the road I guess.
