After driving it around a number of hot bends, I find that the "sporty" oversteer set-up as delivered by the factory might be a little aggressive for my taste. I decided to have the dealer back off the rear sway bar stiffness one notch to the middle hole. I observed some amount of skittishness traversing bumpy corners that had also been reported by some early test drivers. Ben LJ advised me that his CGT was delivered set to the middle hole whereas mine was set conventionally to the stiffest hole. We will see how it changes when the adjustment is made.
Now for the bad part of new cars ... I was unable to avoid a piece of metallic junk in the middle of my street lane that made a slight interference fit with the underside of the car
It looked like the remains of a universal joint, complete with one of the yokes, that had fallen off of, or out of, a passing vehicle.
The CGT has much poorer blind-spot visibility than other cars I've driven and one must do much more neck swiveling than that to which I'm accustomed. By the time I figured out that I couldn't swerve to change lanes and avoid the "thing", all I had time to do was line it up to approximately center it for a "pass over". I briefly considered slamming on the brakes, but there was someone close enough behind that I thought they might hit me from behind.
So, ... I just took my lumps.
Well, ... we put it up on the lift at the dealer to have a "look/see". The ferrous "thing" clipped the front spoiler strip and put a barely visible gouge in the lower lip. I can live with it easily as-is.
Further back, however, the "thing" must have flipped from contact with the spoiler lip and made hard contact with the fore-most bottom CF panel. It punched a small variegated hole that won't quite admit my little finger all the way through the carbon fiber panel. It also scraped its way back along most of the under-tray, leaving surface scrape marks all along the way.
If I were to replace all the damaged panels for cosmetic reasons, the dealer parts guy got a quick bill together equaling the better part of a new Boxster. The mid and rear under-tray panels were $17K each, while the front panel with the molded in brake ducts, etc., was about $10K.
I was briefly tempted to buy a new front under panel when I imagined it might be only $5K, but in light of the nature of the damage, I've opted to cover the little hole with some black duct tape to prevent any road-liquid ingress or snagging of the free fiber ends. I won't replace the panel until it's been banged up some more (to which I've resigned myself is certain at some point).
Here's the little puncture:
