While everyone has been very nice, my Z8 is back at Peter Pan for the 3rd time as a result of the performance package install. The first visit was to instal the package. When I got the car back, it was undriveable because they hadn't checked that the headlight levelling mechanism was working. The headlights pointed down at about a 15 degree angle and the beam buried itself in the road 25 feet in front of the car. They were apologetic and gave me a 325 convertible to drive while they worked on my Z8. When I got it back, everything was fine, except that the right headlight unit wasn't flush with the hood of the car. Worse yet, every time I looked out the windshield, I saw the back edge of the light sticking up above the hood. I could put up with this (maybe) on a lesser vehicle, but things had better be put together properly on a $100K automobile! So back it went.
At least I got a 5-er from them as a loaner. It's a pleasant drive, except with in 525 form it is somewhat of a dog. The interior is comfortable if a bit industrial, and the best thing is you can't see the outside from the inside.
