So I am a Porsche owner again!
The title has been transferred and funds have changed hands. The car is still in Longwood however, as the shop won't be able to take it until next week.
Last choice I have to make is tires. The two options I get from Tire Rack for 19in wheel diameters are Continental Extreme Contact DWS 06 Plus and Michelin Pilot Sport All Season 4. I have had good experiences in the past with both brands.
