Good Newwwwws everyone! (At least regarding the Boxster)
The garage test drove the car and ran tests on the oil and coolant and found nothing wrong with it. They passed off the incident as just being one of those times a Boxster blows some smoke. Oil was less than a half quart low.
I picked it up and no charge for checking it over.
However on the way there, the Jeep began to boil over and so I had the Porsche shop check it out. Cracked head (which apparently the 4.0 jeep engines are very prone to).
So to recap:
Porsche: Fine.
Jeep: Awaiting a new head at the shop.
Crazy day to say the least.
